True DPRAM IP

Hi Dave!

Thanks for your fast reply. I really appreciate.

I've been using DPRAMs a lot, it always worked very well.

Actually, it might be a simulation problem, but not sure.

Please find here attached a ZIP with:

-- MegaWizard DPRAM

-- Test bench

-- Stimulus pattern (from text file)

As seen in the stimulus, the sequence is as follows:

1) Write something to address 0, do this twice, I know that the first write cycle is not valid

2) write some addresses in a row

3) switch to read and set input data to a different pattern

4) perform some read operations and read back the address of the first read operation which has been written by erroneous data

There's also a ModelSim screenshot

Thanks in advance for your expertise!

Kind regards

Thomas
