Can't execute "coredecode -in decode > coredecode.e"

[Jeremy-Jia]

// file "decode" is human readable file that has all of the instruction decodes defined and is part of git repo
// modify this file as needed

// to generate all the equations below from "decode" except legal equation:

// 1) coredecode -in decode > coredecode.e

// 2) espresso -Dso -oeqntott coredecode.e | addassign -pre out. > equations

I just read the annotation, but the "coredecode -in decode > coredecode.e" is a commandLIne or something? I cant execute it, should i install some packages for serving these?
thank.

Hi
The coredecode is a perl script and you can find it here
https://github.com/chipsalliance/Cores-SweRV-EH2/blob/master/tools/coredecode
I haven't used it by myself though

Thanks
That does work!

From where I can find the espresso tool?

Hi @zeeshanrafique23 . You can find the espresso source here https://ptolemy.berkeley.edu/projects/embedded/pubs/downloads/espresso/index.htm Last release was in 1988 and there exists some modern reimplementations on GitHub and as Debian packages too

Hi @olofk
I tried this earlier but it was throwing some errors during make.
I tried this repo also https://github.com/classabbyamp/espresso-logic but when I make it create the object files of C files, I not sure how to use it further. I want the executable which I can run directly as a command.

Hi @zeeshanrafique23
I remember using the link shared by olof for espresso but if you face some errors
try using the executable directly from this link http://users.ece.utexas.edu/~patt/06s.382N/tutorial/espresso_manual.html
change the espresso.linux file to espresso and make it executable by using chmod command

Great, thanks @vignajeth it's working. Getting another error while running the espresso command, which does make sense but how to get rid out of it?

$ espresso -Dso -oeqntott coredecode.e | addassign -pre out.  > equations
 addassign: command not found

[vignajeth]

The addassign is a perl script and you can find it under tools folder

Ahh got it many thanks.
