In reply to mayurkubavat:
I prefer the dirst option you have suggested.
I wrote in the compile script the following:
vmap work work
vlog +incdir+./uvm-1.2/src ./uvm-1.2/src/uvm_pkg.sv ./uvm-1.2/src/dpi/uvm_dpi.cc -ccflags -DQUESTA\ pakmx_config.sv pakmx_sequence.sv pakmx_agent.sv pakmx_env.sv pakmx_test.sv pakmx_driver.sv pakmx_pkg.sv pakmx_tb_top.sv
vlog -vs +incdir+./uvm-1.2/src/uvm_macros.svh
vlog design_hdl/packet_mux.sv
vlog pakmx_if.sv
but I still got errors.
