Tree Multiplier Generator for VHDL and SystemVerilog

This tool generates Wallace and Dadda tree multiplier in hardware description language VHDL and SystemVerilog.

Tools

The installation scripts of necessary tools are located in directory tools. These scripts need root permission in order to install packages and tools for simulation. Please run these scripts in directory tools locally.

Design Files

After running one of below commands the automatically generated design files are located in src/verilog and src/vhdl.

Options

N, M are for dimension of input vectors and MAXTIME is for number of iterations.

mult-tree's Issues

Question about using verilator!

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.
