Some tools supporting SystemVerilog don’t support some features. Code generation can be customized by configuration of Veryl.toml to support these tools.


String parameter

Vivado don’t support parameter which is typed as string.

parameter string a = "A";

So you can use implicit_parameter_types like below:

implicit_parameter_types = ["string"]

By the configuration, the generated code becomes like below:

parameter a = "A";
