genus include `define file

You can parse your define.vh, convert it to a single string, and put it into the -define option of read_hdl command.

Assume you have a file consist of only `defines. For example:

`define SYNTHESIS

`define MACRO_1 5

`define MACRO_2 1'h0

`define MACRO_3

You can use this or something like it:

proc parse_verilog_define_file {file_with_macro} {  

  set fp [open $file_with_macro r]  

  set file_data [read $fp]  

  close $fp  

  set data [split $file_data "\n"]  

  foreach line $data {    

    lappend processed_data [string map {" " =} [string trim [string map {`define ""} $line]]]  

  }  

  return $processed_data

}

set macro_string [parse_verilog_define_file "define.vh"]

# result: "SYNTHESIS MACRO_1=5 MACRO_2=1'h0 MACRO_3"

read_hdl -define $macro_string -sv top.sv

Hi that worked, thanks a lot for the solution. I've used your solution in my script, but the last few days I tried the following and surprisingly parsing it as a list worked which I didn't expect because parsing them line by line did not work using read_hdl.

read_hdl -sv {define.vh top.sv}
