ISE wishlist

This is for the Xilinx guys on the newsgroup (sorry if you've heard this before):

Could you make Picoblaze a standard part of ISE distribution? All it takes is to include the assembler and to make ISE recognize the .PSM files and at build time, assemble them to VHDL files and include it with the rest of the project. Maybe to also make Picoblaze into a Coregen block. Any thoughts?

Thanks.

Hi Jim,

I have my own wishlist too, but what you suggest is not on my list, and I doubt will be implemented they way you suggested.

1) Xilinx politics: ISE is FPGA tool, EDK is embedded development tool. So picoblaze would not be integrated to ISE 2) A few releases ago it was possible to create own cores for coregen, with latest ISE releases this seems to be more hidden than it used to be. Picoblaze could be added to coregen, that would be possible - unfortunatly I can not do it (see before it was possible in ISE 5.x) 3) All the 'integration' actually isnt so necessary - all that is needed is the ability of DATA2MEM to initialize the parity bits (sorry maybe that is fixed in 7.x I havent checked). So you can just add the picoblaze with empty BRAM and run a batch/shell script that uses DATA2MEM to combine the .PSM into the ISE generated .BIT, pretty much similarly as EDK is doing it.

antti PS I basically agree with you that the way PicoBlaze can be used is not very easy, a lots of looking for what to download, fill up forms, ... all pain :(

I'm not too familiar with Xilinx politics, etc but the way I see it (heck, the way Ken Chapman sees it), Picoblaze is meant to replace state machines which have got too hairy to do the usual way, not the kind of stuff Microblaze/PPC is meant for.

Yeah, I read the XAPP, tried, and failed. I now do things the hard way (instantiate LUTs and FFs, and apply attributes in VHDL).

So if all that's needed is this, just include one tiny button in ISE to do this... can't be so hard, can it? If any such scripts are freely available, please point me to them. Thanks!

-Jim
