Hi, I'm new to Xilinx devices and tools so please bear with my ignorance.
I have an on-chip component that interfaces off chip devices (ADC's, etc.) to the Microblaze processor. The interface is precisely a port of a dual-port BRAM.1) Initially, I thought it would be easiest to simply map the various signals into GPIO of the Microblaze (speed at this point is not important, getting something running is). But the GPIO seem to only want to talk to the device pins. Anyone know how to insert a component between GPIO and device pins?
2) I've also tried to use a memory style interface using either the OPB-to-BRAM controller or the LMB-to-BRAM controller. However, no "Wizard" or component instaniator will fill in all the parameters correctly, and if I try to modify the files (*.mpd or wrapper *.vhd) either they get rewritten over with the original incorrect values or won't compile. Any suggestions on working this interface will be appreciated.
Thanks for any help.
