First, please read
Can I use veri_file::Analyze to read System Verilog input files one by one?
Yes. But if you have multiple files, it’s better to use veri_file::AnalyzeMultipleFiles().
veri_file::AnalyzeMultipleFiles(), besides analyzing each files, also:
- opens and ends the compilation unit
- processes –v and –y options
- removes include directories
- processes root module
- undefines user-defined macros
- resets compile directives (e.g. `default_nettype, `timescale)
If you use veri_file::Analyze() to analyze files one by one, after parsing all the files and before elaboration, you’ll need to call these APIs:
- veri_file::ProcessUserLibraries()
- veri_file::RemoveAllIncludeDirs()
- veri_file::EndCompilationUnit ()
