VIRTEX v Spartan 3

recognise

The JTAG programming cable supplied with the kit is a Digilent JTAG3 cable. In connects between the parallel port on a PC and the JTAG connector on the board. It is directly compatible with the Xilinx iMPACT software.

Correct. The PicoBlaze 8-bit embedded controller core is available at no-charge. The newest version for Spartan-3, Virtex-II, and Virtex-II Pro includes a few new instructions and a 64-byte scratchpad RAM. The core and user guide are available via the following link. Unfortunately, the Xilinx site asks you to register before you can download the PicoBlaze VHDL source.

The 32-bit MicroBlaze RISC core is part of the Xilinx Embedded Development Kit (EDK), which includes other development software and IP cores.

I remember (from about 1977) someone with a whole box full of a popular Intel DRAM chip, maybe 16kbit, but without any markings on them at all. I believe donated to the university, as you say.

Do your ES parts have labels on them?

Glen,

Yes they do (have markings). All of our ES parts are marked clearly as ES:

or

(CES is sometimes used interchangably with ES)

We generally use laser marking now on all of our components to make it more difficult for someone to clone the markings.

Why would anyone want to make a counterfeit FPGA? So they can get your money before you discover the parts are empty.

Another really good reason to only buy from a qualified distributor.

Speaking of shoe boxes, in 1974, Gordon Moore came by UC Berkeley with a shoebox of 1702 EPROMs where only half of each one was good. Sometimes universities get some pretty useful stuff, but mostly not. We also had Western Electric #24 PNP germanium transistors donated by the old Bell system.....
