problem in clock input in virtexpro/spartan3a/spartan3 kit
hi In virtexpro/spartan3a/spartan3 kit when we using system clock(100Mz/50Mhz) and take this clock on i/o pin(by writing VHDL program) on digital C.R.O. it will show corrupred signal , I also tried this by DCM CORE GENERATOR again it is giving wrong o/p. Can anybody suggested me solution of this problem. ... 14 May 2010 19:23
Xilinx Synthesis Tool generates clock signals from combinatorial logic
Hello, I am facing a problem of clock signals being generated by combinatorial logic. Here is the timing report: TIMING REPORT NOTE: THESE TIMING NUMBERS ARE ONLY A SYNTHESIS ESTIMATE. FOR ACCURATE TIMING INFORMATION PLEASE REFER TO THE TRACE REPORT GENERATED AFTER PLACE-and-ROUTE. Clock... 19 May 2010 10:25
New 'standard' compact programming header needed!
15 years ago a 2x5 pin 0.1" pitch through hole programming header wasn't excessively large, these days it's a bit of a joke, worse if you use a surface mount part. It would be good to have a more compact 'standard' surface mount programming header. I've used Molex Picoblade vertical headers and connectors reas... 19 May 2010 18:14
ModelSim XE III error
Hi all i'm suing ISE 11.4 and ModelSim XE III when i do the behavioral simulation it works well but when i do the post place & route simulation the ModelSim report this errors "# ** Error: netgen/par/fpu_double_timesim.vhd(45842): (vcom-1141) Identifier "x_dsp48a1" does not identify a component declaration." h... 11 May 2010 15:37
what is the fmax of the simple dual port ram in the altera fpga
I used the simple dual port ram in quartus with the altera fpga,but when i simulate it in 100Mhz, the read data isn't what i haved writen in. but the classic timing analyzer shows the fmax is about 200Mhz.could anybody help me. I am so bothered with it. --------------------------------------- Posted ... 12 May 2010 06:56
Expecting sequential output, but RTL shows concurrent implementation.
> Sorry for hijacking the thread, but... do you mean that if I write this code: signal foo : std_ulogic_vector(3 downto 0) := "1010"; I would *not* normally expect the FPGA to power up with "1010" in the signal!? I've only ever worked with Xilinx FPGAs using ISE, so I assumed it worked everywhere; is thi... 18 May 2010 13:38
Two PCIe Endpoints in one Virtex-6?
Hello, I had a look into the V6 Datasheets, but couldn't find a direct clue. Would it be possible to implemement two PCIe Endpoints in one Virtex-6 FPGA? Most of the V6-Devices offer two hard PCIe blocks and the PCIe root device should initiate link training on all lanes. If I understand this correctly, it shoul... 14 May 2010 07:19
