Thanks to a project at work I was exposed to Xilinx's 9500 series CPLDs. There are GREAT to work with, very easy to get going with them. The software is free and includes both Verilog and VHDL support, programmer software and a good sim. The programmer itself is pretty simple to build (although I used the programmer we have at work). As for language I personally prefer Verilog, by a large margin. Coming from a programming background Verilog seems more "natural" to me, it's quite "C" like in the way it does things. VHDL is OK, but I was just never very comfortable with it. Hope this helped. TTYL -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Both Xilinx and Altera offer small free packages online to start with development. Seems that in the states, west of the mississippi verilog is used, and east of it VHDL is used. I prefer verilog myself. Now, withe the Altera s/w for the 7000 series parts, you can do schematic capture if you don't have an interest in learning an HDL, but I would recommend that you do learn it. Most large designs are done in HDL {Quote hidden}>From: Herbert Graf <spam_OUTmailinglistTakeThisOuTFARCITE.NET> >Reply-To: pic microcontroller discussion list <.....PICLISTKILLspam@spam@MITVMA.MIT.EDU> >To: PICLISTKILLspamMITVMA.MIT.EDU >Subject: Re: [EE]: FPGA's CPLD's etc....starting point >Date: Fri, 7 Feb 2003 01:34:27 -0500 > > > Can anyone on list offer any pointers for someone looking at getting >into > > programmable logic?

See http://www.piclist.com/#topics You can take a look at Altera website, you can use the most advanced tool in FPGA programming using Quartus II, with a very nice interface. Also they have many chips to work with. And I program VHDL (don't know much Verilog) is very easy, but you have to remember to program a circuit, you are not programming a software program. You program a RTL logic or a behaviour. And an ISP programmer is byteblaster, very easy to build. With this you have too much to start, take a look at Altera, Xilinx and lately Actel is coming to the consumers side. -- Saludos, Pepe .....zumbita00KILLspam.....yahoo.es ___________________________________________________ Yahoo!

if you only want to use relatively small fpgas, it makes no sense to use altera quartus software. you better use altera maxplus, which is an older tool, but may give you better results for chips of the max3k or max7k technology. although i do fpga design every day, i usually take maxplus (for chips up to 30kgates). tino Pepe Benitez <zumbita00spam_OUTYAHOO.ES> Gesendet von: pic microcontroller discussion list <@spam@PICLISTKILLspamMITVMA.MIT.EDU> 10.02.03 12:05 Bitte antworten an pic microcontroller discussion list An: KILLspamPICLISTKILLspamMITVMA.MIT.EDU Kopie: Thema: Re: [EE]: FPGA's CPLD's etc....starting point Estimado Herbert, Con fecha viernes, 07 de febrero de 2003, 7:34:27, escribis: >> Can anyone on list offer any pointers for someone looking at getting into >> programmable logic?

The 3.3v (XL series) version is a little bit better than that in practice (~25% lower). It's still not an ideal family for long lived battery powered devices. The coolrunner family is spec'd better for that, but you'd need level converters if your other hardware isn't 1.8v-2.5v. These are loads better than the old style gals/pals I used in school. They are way more hardy and don't get nearly as hot when pressed. I'm not sure why, but I could always get my AMD PAL22V10's to "forget" after a while. That kind of soured me on programmable logic for a while. (the cypress versions I worked with later did work better). Still, these xilinx components are quite a bit more reliable for me. I used the altera parts before these and they worked handily, but I got irritated with them when they took out verilog support of the free dev package. It turns out that I can get the xilinx parts easier/cheaper anyway. {Original Message removed}
