Accessing LINUX environment variables in verilog-AMS/verilog-A

What are you hoping to do with these environment variables? Maybe you don't need to evaluate them - for example, the $fopen() function will accept paths containing environment variables and read/write files with the evaluated values of those env vars.

How are you doing it in SystemVerilog?

Hi Andrew.

In short, import "DPI-C" function string getenv(input string env_name);

Here it is in SystemVeilog, the full thread.

I was trying to get certain printouts done when an environment variable was set.

Thanks.

I don't think this is possible with Verilog-A (I didn't check with Verilog-AMS). You might have been able to do:

import "CDS_VA_DPI" function string getenv(string varname);

except that this approach doesn't support string return values or string arguments.

I think you would need to contact customer support for an enhancement.

Andrew.

Thanks Andrew.

Happy new year!
