We developed a desktop application using wxWidgets While developing we had succesfully made :

1. GUI (which can currently be runned on windows- for other OS , solution is given below )

2. Stimulator which can parse the RISC-V code

• We are unable to use stimulator built upon standard library with GUI made with wxWidgets , so we are trying for another solution or we can say we made both but not able to fuse them !
• We had problems with integration of this with Other OS ( especially Mac ), we can assure it works on all window version's

Download the zip file (or) fork this repository and use git clone to clone it on your local desktop

Go to release folder and click on wxBits.exe file ( remember only for window's )(Installer Link is also available )

If there is a prompt from Windows security click on runanyway Here you go-wxBitsapp running!!

If in anycase , .exe files is not supported in your OS, then click on (.sln) file and build solution in release mode (if wxWidgets installed in your system )

Open Stimulator Folder

Open input.txt file copy and paste any of the samplecode or bubblesort or type any Risc-V code

This folder has pf.cpp (pipeline forwarded) and pwf.cpp (pipeline without forwarding)

Open the the file of your choice (pf.cpp or pwf.cpp) in vsCode or any editor and run it

You can see a new file in the same stimulator folder named output.txt will be created

output.txt files contains the result of execution

1. It contains all the values of registers
2. contains the memory values
3. Number of cycles,Number of instructions,Number of stalls,Instructions per cycle
4. Pipeline diagram

1. Memory is byte addressable

• pipeline diagram for larger input maynot be readable but is correct.To test the accuracy try using smaller inputs
• for referance try the codes in sample codes folder
