Use examples with native UVMC

UVM

Hi,

Some tools (such as Questa Ultrasim 2019.3_2) have UVMC 2.3.1 already compiled natively with the factory installation.

UVMC 2.3.1 comes with a lot of examples.

However, I was not able to run neither the examples in the UVMC 2.3.1 Kit nor the examples contained in the factory installation using the native precompiled UVMC library of the tool. Using run_questa or Makefile.questa, the UVMC library is compiled again and the native precompiled tool library is not used.

My environment variables are:

export MENTOR=/usr/local/mentor
export BITS=64
export QUESTA_HOME=$MENTOR/questa_sim-2019.3_2/questasim
export MGC_HOME=$QUESTA_HOME
export MTI_HOME=$MGC_HOME
export MTI_VCO_MODE=$BITS
export MTI_BYPASS_SC_PLATFORM_CHECK=1
export UVM_HOME=$MGC_HOME/verilog_src/uvm-1.1d
export UVM_LIB=$MGC_HOME/uvm-1.1d
export UVMC_HOME=$MGC_HOME/verilog_src/uvmc-2.3.1
export UVMC_LIB=$MGC_HOME/uvmc-2.3.1
export PATH=$QUESTA_HOME/bin:$PATH

However, using modified files run_questa_native and Makefile.questa_native, I was able to use the precompiled native tool library.

File examples/commands/run_questa_native reads as:

# . . . 
rm -rf work
vlib work

# Compile example ...
vlog -sv -L $UVM_LIB -L $UVMC_LIB +define+QUESTA sv_main.sv
sccom -DSC_INCLUDE_DYNAMIC_PROCESSES -DQUESTA -I$UVMC_HOME/src/connect/sc ex_phase_control.cpp
sccom -uvmc -link

# Run example ...
vsim -c -do "run -all; quit -f" -t 1ps -L $UVM_LIB -L $UVMC_LIB -l questa.log +PHASING_ONE sc_main sv_main
# . . .

File examples/commands/Makefile.questa_native has two lines changed with respect to Makefile.questa:

MAKE_CMD = $(MAKE) -f Makefile.questa_native
include ../common/Makefile.questa_native

The files in the remaining directories are changed in a similar manner.

File examples/common/Makefile.questa_native has two lines changed with respect to Makefile.questa:

VLOG  = vlog  -$(BITS) $(OPT_C)  -sv -L $(UVM_LIB) -L $(UVMC_LIB) +define+QUESTA
LINK  = sccom -$(BITS) $(OPT_L)  -uvmc -link

Elmar,

Thank-you for your input.

By and large, the UVMC examples are designed to be allowed to re-target to
different gcc compilers so they are primarily based on the assumption
that the user will first build the $UVMC_LIB using the compiler of choice
then run the examples using the $UVMC_LIB just compiled.

However I’ve downloaded your tarballs and reviewed them. For the uvmc-2.3.2
release we will consider some simplifications that will allow the examples
to be run either using the pre-built libraries or explicitly compiling
them to a separate $UVMC_LIB using the selected ambient gcc compiler.
