General Description: When I simulate a design with CORE Generator Dual-Port Block Memory, the simulator reports the following message:
WARNING [STX-RNGDEF]: /nfs/ibu_apps/xilinx/E.30/verilog/src/XilinxCoreLib/BLKMEM- DP_V3_0.v, line 783: module BLKMEMDP_V3_0, instance ao16f_fifo32x32_1rs_1w.uMEM.inst, Design Error: Out of range memory select on pipelinea. [1] is selected, but only [0:0] is defined.
Solution
The problem is in Verilog behavioral model "blkmemdp_v3_2.v" and earlier versions of the "dp blk" memory. This problem will be fixed in Dual-Port Block Memory v4_0, which is scheduled to be released in the E_IP1 update in late October, 2001.
