MIG v3.1, Virtex-6 - "# ** Error: (vsim-8604) NaN results from division operation"
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 successfull data comparision. This error appears for all data widths.
This error does not affect the functionality of the simulation and can be safely ignored.
