    question about PNS and PNA in ICC

    Hi How do you call synthesize_fp_rail? and that would be nice also to see your set_fp_rail_constraints calls.

    ICC help --- dc not loaded??

    Hi I don't know what does your error mean. But I use derive_pg_connection to make logical connection between Power pings and power nets. In my flow, first I create power pins and power nets through the UPF flow then I make connections using derive_pg_connection -create_nets and then...

    want to interface fpga as spi mastrer with gyroscope IC

    fpga as spi mastrer hi u can use the core provided by opencores or the opb spi core provided by edk in the case u r going to use microblaze or u can use picoblaze and develop it urself straight forward and easy

    Tested circuits for filtering voice

    FILTER headman333 i belive a digital filter can help u much more i know u r not going to use a dsp inside ur circuit , but i think u can do the required processing at PC side , better than that, is to use a dsp. so, u just put a low pass filter on the signal comming out from the main...

    SD card USB Controller

    simplified_physical_layer_spec ckshivaram complete SD card specification is available here : **broken link removed** one can simply develope an FPGA/microcontroller based application to write to SD card as well as read from it i think it is better for u to study this beautiful page of Wiki...

    ARM LPC 21XX programming

    lpc21xx tutorial it is so easy u can program the chip using a simple serial connection to ur PC using linux, there is a complete toolchain for compiling, debuging and programming the device it really does not need any special tutorial u just connect the suitable chip's pin to ground, and...

    1.5/3/6 MHz Clocks from 50 Mhz On-board Clock using PLL ...

    well, i think that firefoxPL has solved your problem, any how, using a sparatan 3 device, your desired clock frequencies are easily achievable using the CLKDV and CLKFX outputs of DCM if the problem is still remaining tell me and i'll tell u how to set the parameters

    Connecting FPGA & DSP

    LOL! are the DSP board and FPGA board separate boards? Why you want to connect them with ethernet ? it is funny. you can use DSP's McBSP as you know and develop the suitable module on FPGA side you can use Host Port Interface also there are other means like I2C ( don't knoe if the DSP has...

    ISE 9.2i VHDL editor problem.

    interesting! solution : Do not use ISE's editor for writing code, use either Textpad or Notepad++
