Version Found: 3.91

Version Fixed: Never Fix: This issue is present in ISE14.7 v3.92

In the generated MIG Spartan-6 MCB design, line 3381 of the mcb_raw_wrapper. file incorrectly assigns the p1_wr_error flag as follows:

         assign p1_wr_error    = mig_p5_error | mig_p5_error;

Solution

The correct logic should be as follows:

          assign p1_wr_error    = mig_p3_error | mig_p5_error;

This is because the write path of the second port uses p3 and p5.
