Product Line: LogiCore
Product Part: Coregen IP Modules
Problem Title:
2.1i, V1.5, V1.4 COREGEN: "WARNING: Core 12x12_Multiplier (8x8_Multiplier) did not generate
product VerilogSim"
Problem Description:
Urgency: standard
General Description:
When generating the 8x8 or 12x12 Speed Optimized Multiplier with "Verilog behavioral model"
selected as a desired output, the warnings similar to the following are seen (the 12x12
multiplier warnings are shown here) :
"WARNING: Core 12x12_Multiplier did not generate product VerilogSim.
WARNING: Warnings and/or errors encountered while generating
12x12_Multiplier (12x12_Multiplier 1.0) All output products requested may
not have been generated.
The warning is seen because Verilog behavioral models are not available for
the m8x8 and m12x12 speed-optimized multipliers .
Solution 1:
The workaround is to do a post-NGDBUILD Verilog functional simulation of the module.
See (Xilinx Solution #8065) for more information on how to generate a post-NGDBUILD
Verilog simulation netlist.
