Hi, I often see some FPGA positions requiring Python, Perl. What use of these scripting language? I know TCL used in FPGA tool chain. I am very curious about it? Thanks,
What use of Python, Perl in FPGA development?

Hi, Around the tools (that indeed have usually TCL included) are often a wide variety of additional scripts to help you automate your designflow in several aspects (eg. code generators, make-mechanism, filter tool reports, manage regression tests,.... ). For these scripts is usually Phyton and Perl required, as TCL is not very compfortable. regards Thomas

One example is the hdlmake project[1]: a very nice HDL project manager, bui= ld in Python. It allows you to flexibly manage multi-language and multi-pla= taform projects. Another example is MyHDL[2], a python-based HDL code generator[2].

This is the kind of project what I was looking for my DSP testbenchs! = For some time I had the feeling that Python would be ideal for testbenches,= and this just fits my dream. Thanks for sharing, I'll test it soon!

It really looks like an excellent tool. I am still new to Linux.I download the first (hdlmake-v1.0) from the below = 4 files. And put it under ~(Home) directory in Ubuntu 12.04 LTS. I can rename the full hdlmake-v1.0 to hdlmake (as in its tutorial of the author)? hdlmake-v1.0 05/05/2013 15:20 37 kB 184 =09 hdlmake-v1.0-isyp 05/05/2013 15:21 40.8 kB 53 =09 hdlmake-v1.0-isyp.tar.gz 05/05/2013 15:20 220.3 kB 62 =09 hdlmake-v1.0.tar.gz 05/05/2013 15:20 100.5 kB 126

Cloning the repository If you prefer to get the source code, you need to have the popular Git vers= ion control system installed on your machine; if you don't, this page offer= s details on how you can configure Git to clone our repositories. Assuming = you have Git installed, running the following will clone (download all file= s in the) repository to a folder named hdlmake under your /home/user_name/ = folder: $ git clone git://ohwr.org/misc/hdl-make.git hdlmake Now you're almost ready to go. You can run hdlmake by changing directory to= a desired location and running $ python path/to/hdlmake/hdlmake

Later, if you want to, you may put the directory in the $PATH environment v= ariable so you won't have to use the full path every time you use the tool.= Google how to do it, it is a very common task.
