VHDL for ECE 281 Lab 2
Targeted toward Digilent Basys3. Make sure to install the board files.
Tested on Windows 11.
Follow the instructions to Create a new Vivado Project. Suggested name is binaryHexDisp.
Then add all the files in src/hdl/
to the project, as described here
The workflow uses the setup-ghdl-ci GitHub action to run a nightly build of GHDL.
First, the workflow uses GHDL to analyze all .vhd
files in src/hdl/
.
Then it elaborates the any entity with the name *_tb
. In this case, that is helloled_tb
.
Finally, the workflow runs the simulation. If successful then it will quietly exit with a 0
code.
If any of the assert
statements fail with severity failure
then GHDL will cease the simulation and exit with non-zero code; this will also cause the workflow to fail.
Assert statements of other severity levels will be reported, but not fail the workflow.
