Running UVM with Questasim in Cygwin(Windows)

I am using the following steps :

i) First copy the win32/64 folder folder from Questasim installation path for DPI library. Point to that path using -sv_lib switch.

ii) For running UVM with Questasim in Cygwin path for include files have to be given in relative path format.

This is because Questasim cannot understand $UVM_HOME=/home/uvm-1.1d POSIX like path.
So for running the ubus example in uvm-1.1d go to  ubus/examples and run following :


vlog -timescale "1ns/1ns" -mfcu -suppress 2181 +acc=rmb -writetoplevels questa.tops +incdir+../../../../src ../../../../src/uvm.sv +incdir+../sv ubus_tb_top.sv

vsim -sv_lib ../../../../win64/uvm_dpi -c -do "run -all; q" -l questa.log -f questa.tops +UVM_TESTNAME=test_2m_4s


Also would like to add qverilog command :



qverilog -timescale "1ns/1ns" +acc=rmb +incdir+../../../../src/uvm.sv +incdir+../../../../src+../sv  ubus_tb_top.sv -R -sv_lib ../../../../win64/uvm_dpi  +UVM_TESTNAME=test_2m_4s -c -do "run -all; q" -l questa.log


Found a way to run without DPI and using Makefile 


ii) Avoid DPI as  : make -f Makefile.questa UVM_NO_DPI=1 all
