Has anybody seen an app note that shows direct programming of a Spartan IIE from a PC parallel port without using iMPACT, JTAG or an intermediate device such as a CPLD? I'm building another version of a logic analyzer with a 300k Spartan IIE and using the PC parallel port in EPP mode (bidirectional 8 bit with 6 control lines) rather than Centronics mod

I have previously worked on Spartan IIE boards while at Uni and am now wanting to continue tinkering with them at home to improve my skills. I came across the Spartan 3E Starter board at the Xilinx site for USD150 and am thinking of purchasing it. I intend to start off with some verilog to get me going again (basic stuff) and then I intend to eventually add a PicoBlaze or MicroBlaze or some stu...

However, I get error when I try to re-synthesiz...

I'm working on a project with the Spartan 3 Starter Board and the Xilinx WebPack ISE version 8.2 As I look over the timing results, there are lengthy delays in the paths containing input switches (toggle switches) and digit/segment outputs to 7 segment displays.

I bought a Digilent Spartan 3E Starter Board and it comes with 32M x 16 of DDR RAM. They don't provide a controller core. So I started over at OpenCores and downloaded a DDR core but I haven't even begun to study it. Instead I went to the datasheet... I notice that it takes 2 clocks to get the first word from memory. Then I can get a word every 1/2 clock. It's that initial 2 clocks that ...

I just started playing with Xilinx Spartan 3E (speed grade -4) and I was appalled to find that even with extreme care can I only run the BRAMs at 170 MHz. Anything realistic and the speed drops much further. This is compared to my age-old Altera Cyclone which happily ran north of 200 MHz. You'd need X and A's performance parts (Virtex/Stratix) to get anywhere near 300 MHz. Xilinx Virtex 5 claim...
