Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 6: Using NC-VHDL with Synopsys ModelsNoteMake sure there is only one fmiLibraryTable among all the objectscombined into the libfmi.so file. You can use the UNIX nm command (andC shell) to do this:foreach obj ( )nm ${obj} | grep fmiLibraryTableendIf fmiLibraryTable is defined more than once, the libfmi.so will probably beunusable.5. Use NC-VHDL to compile and elaborate your design:% ncvhdl testbench.vhd% ncelab testbench_configuration6. Set the LMC_TIMEUNIT environment variable to -12 for 1 ps resolution:% setenv LMC_TIMEUNIT -12This sets a global timing resolution for all SWIFT models in your simulation. Formore information on the LMC_TIMEUNIT environment variable, refer to theCadence documentation for NC-VHDL.7. Set your LD_LIBRARY_PATH (Solaris) or SHLIB_PATH (HP-UX) environmentvariable so the working directory where you created the new libfmi.(so|sl) is first onthe library directory path list.% setenv LD_LIBRARY_PATH ":${LD_LIBRARY_PATH}"8. Invoke NC-VHDL to simulate your design:% ncsim testbench_configurationFor NC-VHDL Version 4 or HigherFollow these steps to use NC-VHDL (version 4 or higher) with VERA and DWMMmodels.1. Set the dynamic library search path to look first in the VERA library directory, andthen in the LMC_HOME solaris library:% setenv LD_LIBRARY_PATH"${VERA_HOME}/lib/nc_vhdl:${LMC_HOME}lib/sun4Solaris.lib:${LD_LIBRARY_PATH}"2. Use NC-VHDL to compile and elaborate your design:% ncvhdl testbench.vhd% ncelab testbench_configurationOctober 6, 2003 Synopsys, Inc. 119
