When M1.3/M1.4 XSI is installed, if the version of Synopsys is newer than v3.4b, the M1.3/M1.4 XSI simulation libriaries must be re-compiled before using them. In the Synopsys toolset, M1 simulation libraries must be recompiled with the current version of Synopsys in use.
(If the version of Synopsys used with M1.3/M1.4 is 3.4b, then the M1.3/M1.4 software just has to be installed. No re-compilation of the XSI XDW and XSI simulation libaries is needed.)
During recompilation of the M1.3/M1.4 simulation libraries with a version of Synopsys newer than v3.4b, the user may see the following messages:
After checking all of the above, attempt to re-run the analyze.csh, and/or .dc scripts in $XILINX/synopsys/libraries/sim/src
While running the analyze.csh in $XILINX/synopsys/libraries/sim/src/logiblox or in $XILINX/synopsys/libraries/sim/src/simprims, the following message appears:
Error compiling file : ../../lib/simprims/X_XOR6__X_XOR6_V.c, Reverting to Interpreted code for design unit : X_XOR6_V. Warning: vhdlan,1500 /xilinx/vhdl/src/simprims/simprim_VITAL.vhd(6392):
The interpretive re-compilation of the M1.3 XSI logiblox/simprim libraries has succeeded, but the C-compiler based re-compilation has failed.
This typically happens on Solaris platforms but not on SunOS 4.x. Solaris platforms do not come with the cc C-compiler which is compatible with vhdlan -c. The cc C-compiler for Solaris must be purchased from Sun. SunOS, on the other hand, does come with the cc C-compiler which is usually compatible with vhdlan -c.
When this message happens, the user can opt to use the libraries that were created. If the user is simulating a 'small' design, use of the C-compiled or interpretive based logiblox/simprim libraries will probably not make a big difference in simulation time. On the other hand, if the user has a 'large' design to simulate, it is highly recommended that the user get the vhdlan -c option to work.
Please check your Synopsys on-line docs (Iview), or contact Synopsys (http://www.synopsys.com) for information on C-compilers compatible with vhdlan -c.
If you are using Synopsys 3.4b, or later, with Solaris than the C-compiler that should be used with vhdlan -c should be v3.0.1 of the cc C-compiler with the Solaris OS.
What follows is an example of setting up the cc C-compiler v3.0.1 on the Solaris OS. Please consult Synopsys for compatible C-compilers that can be used with vhdlan -c:
After making sure the above settings are correct, in the .synopsys_vss.setup file in the $XILINX/synopsys/libraries/sim/src/logiblox and $XILINX/synopsys/libraries/sim/src/simprims directories add the following line to the .synopsys_vss.setup file:
