5.2 Xsimmake - Error message says to run functional simulation


If your design contains any Xilinx ABEL, X-BLOX, or MemGen blocks, you have to run XSimMake with the functional flow before running XSimmake with the timing flow, if your design contains any Xilinx ABEL, X-BLOX, or MemGen blocks.


The functional flow does a lot of preliminary work that is required for the timing flow. For Viewlogic, it creates both a simulation schematic and a functional VSM file that is necessary for timing simulation.

If you do not have any of these special blocks in your design, then you can just create a VSM file from the schematic. The restriction is that you must have in the current directory all the files needed to create the functional VSM file.
