Description

When simulating all Virtex-6 MIG designs (DDR2 SDRAM, DDR3 SDRAM, and QDRII+ SRAM) using ModelSim, the following error occurs: 

#**Error: (vsim-8604) NaN results from division operation."

Solution

The design completes the calibration and read/write operations with successful data comparison.

This error appears for all data widths.
