This doesn't help if for some reason (e.g. high speed UBS transfer) you already have some device that handles USB access and could handle JTAG. To plug in the DLC(clone) you need another connector ... -- Uwe Bonnes bon(a)elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------
From: John Adair on 12 Dec 2009 11:46 I will add that our new USB based Prog3 is now working. This cable will work with Impact and Chipscope. We do have some more tests to do after which we will release to sell generally with our products. Expect this to be available in January sometime. John Adair Enterpoint Ltd.

From: dlopez on 12 Dec 2009 12:09 Thanks everyone for the feedback...I ended up getting the Digilent cable since it's so cheap. It was news to me that this cable would support chipscope. It sure is better than 250$! Diego --------------------------------------- This message was sent using the comp.arch.fpga web interface on http://www.FPGARelated.com

I can program FPGA's fine with my Ethernet based "programming cable", but I can't interface to chipscope and signaltap. A documented USB interface would not be optimal in my case as I would have to make a some kind of virtual USB device. It would be more optimal to have some method at the Impact/quartus_pgm level to add a programming hardware interface. Petter -- A: Because it messes up the order in which people normally read text.

Interface was meant here as the software interface, API should have been better uses instead of interface... -- Uwe Bonnes bon(a)elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ---------- |
