Hello, I am facing an error in the synthesis step which says:

/openLANE_flow/designs/brqrv_core/src/brqrv_core.sv:16: ERROR: syntax error, unexpected TOK_PARAMETER

This is the line 16 of the code.

15 module brqrv_core (

16     parameter bit                 PMPEnable        = 1'b0,

17     parameter int unsigned        PMPGranularity   = 0,

I dont understand, the syntax looks fine. Is it something specific to YOSYS that I am missing?
