Hey All,
I am working on a relatively large design involving DSP on an FPGA. We use a Virtex4 LX60 and fill up about 50-75% of the LUTs and all of the DSP48s. Anyway, in the process of development I decided to switch my design over to Synplify Pro. I compile the DSP portion of my design which subsequently spits out an .edf file. I then try and include this in my EDK design, as we have the uBlaze running in there and need to use EDK (apparently). However, I get the "portability" error that seems prominent on many designs (as per the Xilinx support website). Basically, it will not accept a generic .edf file into the design unless it is generated using XST. Here are my questions:
- Is it possible to compile the uBlaze outside of EDK?
- I have talked to Synplicity about doing the above, but has anyone ever taken the troubleof compiling a uBlaze design and then shoving it into Synplify Pro? (This is Synplicity's solution, which may work, but will take a while, especially over multiple design iterations)
- Does ISE have a simpler implementation of including all of these peripherals that EDK claims to be speciallized for?
- Has anyone seen the portability error described above before when trying to include an outside .edf file?
If anyone could help me out, and not point me to the Xilinx support line in the process, it would be helpful. Not that I don't like the support line, I just don't want to send all of my code to them (or you).
Thanks for your help!
