vhd2vl.md

1. I need to convert a bunch of VHDL files to Verilog.
2. Found tool http://doolittle.icarus.com/~larry/vhd2vl/
3. wget http://doolittle.icarus.com/~larry/vhd2vl/vhd2vl-2.5.tar.gz
4. tar xzf vhd2vl-2.5.tar.gz
5. cd vhd2vl-2.5/src
6. try make
7. If bison & flex are uninstalled, you should run sudo yum install -y flex bison
8. try make again
9. If you get /usr/bin/ld: cannot find -lfl it case to hard way: fl mean reffer to library libfl.so but you canot search any mentions of this library:

• yum search libfl doesnt work
• yum provides */libfl.so also doesnt work

10. After hours of googling you will know magic cmd: sudo yum install -y bison-runtime bison-devel
11. Profit
