1.3 Obtaining Distribution

1.4 Supported Systems

This version of Verilog::Pli has been built and tested on:

It should run on any system with Perl and VCS or other Verilog simulator with minor porting.

1.5 Installation

  1. `cd' to the directory containing this INSTALL notice.
  2. Type `perl Makefile.PL' to configure Verilog::Pli for your system.
  3. Type `make' to compile Verilog::Pli. If you are not using VCS and get a error about vcsuser.h not being found, you may need to change the include of vcsuser.h in perl_cmd.c to veriuser.h.
  4. Type `make install' to install the programs and any data files and documentation.
  5. If you have VCS, `cd example ; make' to see an example.

1.6 Interpreter

You will need a perl interpreter inside your simulator to make this package useful. A example verilog file, pli C wrapper and all is inside the example directory. This example uses VCS, but will work with minor modifications with Verilog-XL and other Verilog simulators with a PLI.

  1. cd example
  2. make
