You need to have the Xilinx tools, which generate the bitstream. That means you also have to have a design that you implement in the FPGA. What DON'T you know about FPGAs? How much information has your advisor actually given you? Sounds like he's keeping you in the dark. -andy ###### Path: chonsp.franklin.ch!not-for-mail From: Neil Franklin Newsgroups: comp.arch.fpga Subject: Re: Jbits: more info required Date: 31 Aug 2001 23:59:55 +0200 Organization: My own Private Self Lines: 48 Message-ID: <6uwv3jsxes.fsf@chonsp.franklin.ch> References: <9mof5e$9q98@imsp212.netvigator.com> NNTP-Posting-Host: chonsp.franklin.ch X-Trace: chonsp.franklin.ch 999295195 524 10.0.3.2 (31 Aug 2001 21:59:55 GMT) X-Complaints-To: news@chonsp.franklin.ch NNTP-Posting-Date: 31 Aug 2001 21:59:55 GMT X-Newsreader: Gnus v5.7/Emacs 20.4 Xref: chonsp.franklin.ch comp.arch.fpga:9654 Did not get the original post, so answerign to follow up.

I started with 2.4, now 2.5, and never found any bug (apart from the install programs, which suck, 2.6 will not even run under Linux). Just one weakness in the JRoute routing algorithm (reported to Xilinx about 1 week ago, so surely not yet resolved). > > 3. I guess JBits can be used only with a existing bitstream.

Null bitstreams for XCV300, XCV800 and XCV1000 are supplied with JBits. -- Neil Franklin, neil@franklin.ch.remove http://neil.franklin.ch/ Hacker, Unix Guru, El Eng HTL/BSc, Sysadmin, Archer, Roleplayer - Intellectual Property is Intellectual Robbery ###### Sender: eric@ruckus.brouhaha.com From: Eric Smith Newsgroups: comp.arch.fpga Subject: Re: Jbits: more info required References: Organization: Eric Conspiracy Secret Labs X-Eric-Conspiracy: There is no conspiracy.

What DON'T you know about FPGAs? Actually, to use JBits you don't have to have the normal Xilinx tools (or WebPack) at all. You can get a raw bitstream for a part (such as the XCV800) by readback of a real part after reset. And you don't have to have a starting design done with the traditional tools. You can do it all in JBits. Whether a person would *want* to design things this way is another matter. Some people really like it, but most people prefer traditional HDLs or schematic entry.
