Hello,
I am integrating an IP core and i am facing a strange problem. One of the register of the IP core which is R/W register is not writable ..in simulation I am able to write but when ported to FPGA I am not able to write?its default value is also wrong and when I write to one fixed register in that core... its value gets reflects on that register. Reset value of all the register is ok and I am able to read and write all R/W registers except one. What may be the problem?..since simulation results shows that the IP is ok?so I cannot pin point that tell the IP vendor that there is a bug in ur IP?..
Any feedback??? Thanks and Regards Williams
