Question about using verilator!

[seungbinshin]

Hello, thankyou for your amazing work.

I'm currently trying to use your verilog code generator for wallace tree and dadda tree.

However, I'm now in problem with installing requirements.

So far, I finished to run ghdl.sh and verilator.sh...however, I don't have any idea what to do from now on. Can you tell me about details for me to run your generator successfully? Thank you.

Hi, I did write some documentation in repository about execution of make file with some options. I did also fix the compilation osvvm library with ghdl, so the script "ghdl.sh" in tools directory must be rerun again. Sorry for the inconvenience. Best regards

Hello, Thank you for replying.

Maybe after few works with compiler, I think it will work well from now.

However, I want to talk about some additional options; that changes number of input.

For example, make run_mul WALLACE=1 VERILOG=1 SIZE=32 BITWIDTH=25 MAXTIME=1000 or so on.

I think you might be busy for other works, thus I am curious about what part I should focus on within cpp codes to implement those options.

To tell you why I'm trying to implement those options-

currently I'm diving on custom hardware's mac-tree architecture optimizaiton, and our mac-tree is using wallace tree structure. However, It is generated by other developers wallace-tree generator code.

Our wallace tree is just for adding, thus no partial product is required. Input data number varies, and input's bitwidth varies too, but not squre-shaped.(e.g. 64 input, each of 25bit, x1000 test cases)

To test various options, advanced generator is necessary, therefore I found your code.
Maybe your code generates only for one pair of data, then I need to improve more to handle much more datas.

Again, Thank you for advise and fixing it. If you have any insight for this, please feel free to tell me :)

Sincerely,

Well, I'm sorry to keep annoying you...
After setting gcc version as 11.4.0 to support #include , I've got error messages as follows :

I don't have any Idea for those errors...yes... Thanks :)

I've tested installation scripts on Ubuntu 22.04 LTS. Downgrading or upgrading only gcc might not work, because the libraries should be also adjusted. This is not easy. Please contact Verilator developer for more information about compiling tool in different version of operating system. You could also install verilator with your package manager (if exists) and set make file variable (VERILATOR) to the full path of verilator in your operating system. It is better to use latest stable version of Verilator.Am 21.03.2024 06:57 schrieb SeungBin Shin ***@***.***>: Well, I'm sorry to keep annoying you...

Thanks! I'll try other ways. Have a nice day!

I've adjusted my source code and it generates now tree multiplier for inputs with different sizes.
