A Unified FSDB Dumper for Cadence IUS, Synopsys VCS and Mentor Graphics ModelSim Simulators
A new breed of FSDB dumper is provided since Novas 2009.10. Different from previous FSDB dumpers, the new dumper is unified to support a broader range of simulators and versions. Currently, the new dumper can support Cadence IUS 6.2, Synopsys VCS 2006.06, Mentor Graphics ModelSim 6.4b and their later versions.
The new unified dumper is scheduled to replace the old dumpers in the year 2010. However, the old dumpers are still available for a considerable amount of time. For detailed usage on the new dumper, refer to the Linking Novas Files with Simulators and Enabling FSDB Dumping document (<NOVAS_INST_DIR>/doc/linking_dumping.pdf). And, for detailed usage on the old dumper, refer to the Linking Novas Files with Simulators and Enabling FSDB Dumping document (<NOVAS_INST_DIR>/doc/linking_dumping_pre-2010.01.pdf).
Here is a short example showing how to load the unified Novas FSDB dumper using the Synopsys VCS simulator:
l Set shared library search path.
> setenv LD_LIBRARY_PATH \
${NOVAS_INST_DIR}/share/PLI/lib/${PLATFORM}: \
...
l Compile the design and run the simulation command.
> vcs -line -debug_all -P ${NOVAS_INST_DIR}/share/PLI/VCS/${PLATFORM}/novas.tab ${NOVAS_INST_DIR}/share/PLI/VCS/${PLATFORM}/pli.a
> simv
Note that some of the FSDB dumping commands will also become obsolete in the new unified FSDB dumper. The details about what is changing for the dump commands can be found in the "A Unified FSDB Dumper" application note (KB#8192-18) located in the knowledge base of the SpringSoft support website.
