Hi, is any spartan FPGA is in PLCC package?also its availabilty ? I want to use spartan series FPGA & not the any other spartan seris like spartan 2e etc. which sprom should be used?

They are probably still available from Farnell, as well as the configuration devices. Leon.

i want to design the prototype board for spartan series FPGA which is least costly,for master serial mode of configuration i want to use PROM.I am looking for some through hole component like PLCC84 pin & PLCC 20 pin package.can u suggest me some.

PLCC stands for Plastic Leadless Chip Carrier, so it is NOT through-hole. But there are sockets that can convert PLCC to through-hole. Don't expect any modern devices in this package. Too big and too few pins for today's designs. The world changes, not always in the direction one likes... Peter Alfke

Alternative for "your own" stuff: Use a new FPGA - Xilinx Spartan3(E?), Altera Cyclone-II, or Lattice ECP(2?) - in a TQFP package (still solderable by hand). It's not through-hole but it's doable. Good through hole support is mostly a memory. And don't force everything to be 5V.

Sorry, you are right, of course. Really ambarrassing... But it does not change the fact that they are NOT through-hole. Peter Alfke

The PLCC Spartan/SpartanXL is NOT going to be the least costly. Xilinx no longer supports them. To synthesize, you'll need FPGA Express, and the last time I checked, it ran about $15,000.00 - 15K will buy a lot of time at your local stuffing house. "If it ain't supported in a current web-pack, don't use it."

Hi, I thought one can synthesize for Spartan and Spartan XL with Icarus Verilog then tranfer EDIF file to ISE Classic to complete the project. Am I wrong? By the way, the advice here stands too true. Don't start a new project with devices not supported by ISE WebPACK just because you can buy them cheap...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 You are right, although the -tfpga target for 0.8 is a little rusty compared to current CVS of v0_8-branch, and -tfpga is non-functional on the devel trunk. Because the main trunk and synthesis have diverged recently, I've been considering keeping synthesis in the v0_8 branch and fixing/maintaining it there. A fork, if you will. And supporting abandoned parts like this is a excellent use of open source software. Might even be a business opportunity;-) Satoru Uzawa wrote:> Hi, > > I thought one can synthesize for Spartan and Spartan XL with Icarus > Verilog then tranfer EDIF file to ISE Classic to complete the project. > Am I wrong? > By the way, the advice here stands too true.
