chisel-bootcamp's Issues

Binder: Could not find a kernel matching Scala

Lately I've been seeing this error when using the bootcamp on binder with the error: "Could not find a kernel matching Scala. Please select a kernel" with the only option being "Python 3". Did binder change its kernel options/settings recently?

2.5 Classpath and Parametization type issue

I'm running a local installation (following the README instructions) of the bootcamp on Windows 10 Education, and on 2.5 I run into one of two issues: Either "chisel3.package.experimental" is missing from the CLASSPATH (resolves itself by just re-running all, though sometimes re-running causes it to appear) or

"cmd21.sc:14: type arguments [D,U,EO,EI,B] do not conform to trait DspBlock's type parameter bounds [D,U,EO,EI,B <: chisel3.Data]
extends DspBlock[D, U, EO, EI, B] with HasCSR {
^Compilation Failed"

I've replaced any (potential and accidental) changes to the DspBlock section of the code with the LKG on github, and running non-local installation of the bootcamp works, but I'm not sure what I need/should change to get this cell block running locally.

How to deal with the issue of dead kernel?

Hi, I followed the installation guide on Mac.
But I keep facing dead kernel when I opened Jupyter.
Do you know how do debug this issue?

tester2 Jupyter Notebook test output

I've noticed that when all the test cases pass, the notebook outputs

test xxx Success: 0 tests passed in xxx cycles in xxx seconds xxx Hz

While the same message appears even if a test fails, though now accompanied with an exception getting thrown. I'm not sure if this behavior is intended, but I think a successful run should display # of tests passed (alternatively, 0 tests failed), with test failure displaying number of failures.

2.1_first_module.ipynb: Module name

Note that the Name of our module is cmd<#>WrapperHelperPassthrough, which is an artifact of running this tutorial in Jupyter. In your normal code, its name should just be Passthrough. This is an important lesson though - although Chisel does its best to preserve the names of your modules and other hardware components, sometimes it fails to do so.

I think, this is (luckily) not the case anymore:

Parameterized Shift Register Exercise in module 2.4 has incorrect tester

Lines 30 - 40 in the Parameterized SR Exercise

The tester is calling step(1) after checking the output of the SR, therefore checking the output immediately after giving an input without allowing the SR to advance. step(1) should be before expect(c.io.out, state).

The solution given to the exercise is also connecting io.out := nextState, which is incorrect as the SR now has an asynchronous output. This should be io.out := state and will pass with the corrected tester.

2.4_sequential_logic (Exercise: Shift Register) Solution (minor issue)

Really minor point here.

In the exercise description it says,
"Outputs the parallel output of the shift register, with the most significant bit being the last element of the shift register and the least significant bit being the first element of the shift register. Cat may come in handy."

One solution using Cat is:

state := Cat(state, io.in)
io.out := state

the Solution lists:

val nextState = (state << 1) | io.in
state := nextState
io.out := state

Both are valid.

Maybe list both under Solution?

3.6_types: SomeGeneratorParameters class should be redeclared or imported

In Unapply chapter, following code generate an error :

def delay(p: SomeGeneratorParameters): Int = p match {
    case sg @ SomeGeneratorParameters(_, _, true) => sg.totalWidth * 3
    case SomeGeneratorParameters(_, sw, false) => sw * 2
}
println(delay(SomeGeneratorParameters(10, 10)))
println(delay(SomeGeneratorParameters(10, 10, true)))

The error :

cmd2.sc:1: not found: type SomeGeneratorParameters
def delay(p: SomeGeneratorParameters): Int = p match {
             ^cmd2.sc:6: not found: value SomeGeneratorParameters

                           ^cmd2.sc:7: not found: value SomeGeneratorParameters
val res2_2 = println(delay(SomeGeneratorParameters(10, 10, true)))

              ^cmd2.sc:3: not found: value SomeGeneratorParameters
    case SomeGeneratorParameters(_, sw, false) => sw * 2
         ^Compilation Failed

To make it working, I had to go to 3.5 lesson and copy paste SomeGeneratorParameters class just before delay() declaration :

case class SomeGeneratorParameters(
    someWidth: Int,
    someOtherWidth: Int = 10,
    pipelineMe: Boolean = false
) {
    require(someWidth >= 0)
    require(someOtherWidth >= 0)
    val totalWidth = someWidth + someOtherWidth
}

def delay(p: SomeGeneratorParameters): Int = p match {
    case sg @ SomeGeneratorParameters(_, _, true) => sg.totalWidth * 3
    case SomeGeneratorParameters(_, sw, false) => sw * 2
}

println(delay(SomeGeneratorParameters(10, 10)))
println(delay(SomeGeneratorParameters(10, 10, true)))

On Online Bootcamp Instance, Cannot Connect to Kernel

When loading a page in the instance of the bootcamp hosted online at: https://mybinder.org/v2/gh/freechipsproject/chisel-bootcamp/master it will spend a significant amount of time (~30 seconds) attempting to connect to the kernel, and then show the error:

"A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration."

At which point it attempts to restart the kernel and the entire issue repeats. The bootcamp was working until late last week on this exact same machine (using Firefox 73 on Windows 10) and network location, and I have replicated the issue on other people's machines.

FIRRTL Annotations, Target, Transform Example

The current FIRRTL stuff looks great. Judging by comments from attendees at CCC 2018, annotations are still confusing, though. Likely this can be improved with an example that shows:

A Chisel API to emit custom annotations
A FIRRTL transform that consumes these annotations

More advanced concepts would have to touch on:

EliminateTargetPaths
Target syntax

As an step before this, #22 could be fixed and then referred back to.

Make notebooks proxy aware

To execute the first cell of 2.1_first_module inside the environment behind the proxy i have tomake ammonite shell proxy aware and found this solution:

System.setProperty("https.proxyHost","proxy.example.com")
System.setProperty("https.proxyPort","3128")

^---- should be added before importing chisel packages
I haven't tried running the jupyter itself with JAVA_OPTS="-Dhttps.proxyHost=proxy.example.com -Dhttps.proxyPort=3128"

Probably because alexarchambault/jupyter-scala repo is moved to almond-sh/almond and changed a lot.

RingCounter in module 3.5 seems to be orphaned

@grebe @stevobailey - can we go ahead and just delete the cell since its contents seem to be orphaned?

    "class GrayCounter(val bitwidth: Int) extends NoGlitchCounter(bitwidth) {\n",
    "    // todo\n",
    "}\n",

Generated images don't display in Jupyter Lab

Take the example of 0_demo.ipynb:

Inspect Element gives the following HTML output

Apparently the path files/build is mistyped as files/%20build. The bug doesn't manifest itself when I use Jupyter Notebook. I'm not sure if it's a bug of Jupyter Lab or this repository.

This issue is cross-posted at jupyterlab.

Question about optional reset module

HI, in example of optional reset in 3.1, it said "If resetValue = None, which is the default, the register will have no reset value and be initialized to garbage. ".
However, the generated code still contains an always block and doesn't have any reset. The code now is not synthesizable and may be buggy if used. Why don't we just use assertion and don't generate code in that situation?

module cmd9WrapperHelperDelayBy1( // @[:@3.2]
  input         clock, // @[:@4.4]
  input         reset, // @[:@5.4]
  input  [15:0] io_in, // @[:@6.4]
  output [15:0] io_out // @[:@6.4]
);
  reg [15:0] reg$; // @[cmd9.sc 9:12:@8.4]
  reg [31:0] _RAND_0;
  assign io_out = reg$;
`ifdef RANDOMIZE
  integer initvar;
  initial begin
    `ifndef verilator
      #0.002 begin end
    `endif
  `ifdef RANDOMIZE_REG_INIT
  _RAND_0 = {1{$random}};
  reg$ = _RAND_0[15:0];
  `endif // RANDOMIZE_REG_INIT
  end
`endif // RANDOMIZE
  always @(posedge clock) begin
    reg$ <= io_in;
  end
endmodule

Switch to Driver.emitVerilog instead of Bootcamp-only getVerilog

For easy Verilog generation, getVerilog is great, but it leads to questions like: "How do I import getVerilog?" once people migrate out of the bootcamp.

I think this can be trivially switched throughout the Bootcamp to always use Driver.emitVerilog.

Also, probably Driver.emit for FIRRTL (CHIRRTL) generation. It may make sense to add an API in Driver for emitFirrtl so that this isn't terrifically confusing for the bootcamp.

2.5_exercise: Pointer to Diplomacy page is stale.

The URL for the Diplomacy site in the following section of text:

DspBlocks use diplomatic interfaces from rocket. This site (https://www.lowrisc.org/docs/diplomacy/) has a good overview of the basic of diplomacy, but don't worry too much about how it's working for this example.

yields a "404 page not found" error.

The perhaps next closest reference I could find was:

https://github.com/Intensivate/learning-journey/wiki/Diplomacy

It also has a pointer to the same web page:
This is based on the Main Diplomacy Page (https://www.lowrisc.org/docs/diplomacy/)

WaveDrom Integration for Waveform Viewing

WaveDrom has a lot of cool options for visualizing waveforms. This may make sense to investigate how we can use this to better show the activity of a circuit.

3.6 partialFunction practice has an incorrect test statement

partialFunc3 is composed of partialFunc2 (which is defined for i == 2), and partialFunc1 (which is defined for i == 1). Therefore, it partialFunc3 is fine for i == 1 and i == 2, but not i == 0. The current tutorial lists i == 1 as failing.

Shift Register Diagram in 2.4 doesn't match the solution

In the solution, the output depends on io.in, but in the diagram it doesn't.

As this tutorial grows it becomes harder to figure out if errors are introduced. This is a call for a UnitTest facility to be created. Doing some research I found here
I have played with their example tests and it seems to work

it's weird compile result is occurred In the '2.2_comb_logic' chapter

In the case of addition of this example, io.out_add should be 4'h8(or 4'b1000), but it's 4'h0 in the generated verilog code.
I want to make sure whether I missed something or not.
or, is this a kind of bug?
for your reference, I ran this one on Jupyter notebook

plz Add Example: case object extends abstract class with type parameters

I have seen coding examples when a case object extends abstract class. Can you please explain what happens behind the scenes of such construct. like following line from midas repo.

case object AXIDebugPrint extends Field[Boolean]

Adding examples of Rocket Configuration

In Rocket Configuration, we often see things like

Config(site,here,up) =>

Can you please add a chapter that explains this beast?

Some typo

In 3.1: Taking actions based on the type of a variable when “it's” type is unknown or underspecified, for example when
(its)
In 3.2 Interlude: One of the commonly used interfaces provided by Chisel is DecoupledIO, providing a ready-valid interface for transferring data. The idea is that the "sink" drives the bits signal with the data to be transferred and the valid signal when there is data to be transferred. The sink drives the ready signal when it is ready to accept data, and data is considered transferred when both ready and valid are asserted on a cycle.
(should be source)

Boxed error in 2.1_first_module

I got a Boxed Error in 2.1_first_module.
My OS is Windows10. Scala version is 2.12.8 and almond version is 0.2.1 .
Does anyone know what causes this error?
Thanks

[request] Add an example of Chisel Printf

The 2.1 First Module introduces the peekPostTester. It also uses a Scala Println() to show test completion.

It does not however show the most useful testing construct of all --- the magical Printf!

I've gotten feedback from users who keep trying to use Println() to debug their Chisel code and became very confused.

Thanks and keep up the good work!

chisel3_2.13-3.2.0.pom in Load-Ivy.sc Not Found

With a local install of the Chisel Bootcamp launched using "jupyter notebook" on Arch Linux, in the chapter 2.4 on Sequential Logic I recieve the following error when attempting to run the imports for the chapter:
"val path = System.getProperty("user.dir") + "/source/load-ivy.sc"

interp.load.module(ammonite.ops.Path(java.nio.file.FileSystems.getDefault().getPath(path)))

comment given for Width inference of RegNext

In module 2.4

val io = IO(new Bundle {
val in = Input(UInt(12.W))
val out = Output(UInt(5.W))
})

// register bitwidth is inferred from io.out
io.out := RegNext(io.in + 1.U)

In the verilog generated, the register bitwidth is inferred according to the maximum bitwidth of 'io.in'(12 bit) and not 'io.out'(5 bit)
reg [11:0] _T_13;
The comment which you have added is misleading and it will make confusion in Module 3.2 , while using RegNext with mutable.ArrayBuffers

3.4 Neural Net has issues

The description of the neural net has thresholds of 0, but the solution uses 0.5.
