LogiCORE IP Image Statistics v1.0 - Why do I receive block RAM collision errors in my simulation?

描述

Why do I receive block RAM collision errors in my simulation?

"Error: Memory Collision Error on RAMB16BWER ::v_stats_v1_0_tb:sysgen_dut:blk000015af: at simulation time ...... ns.

A read was performed on address 00xx (hex) of port B while a write was requested to the same address on Port A. The write will be successful however the read value on port B is unknown until the next CLKB cycle."

解决方案

This is a known problem with simulation that isfixed in ISE Design Suite 12.3. It isno longer a problem in the Image Statistics v4.0. This does not affect the hardware because the outputs for the block RAM are not being used at the time the collision occurs.
