    Hi I am using a Virtex 7 board and performing a 64 bit ripple carry addition. Can any one help me how do I use chipscope along with this program of mine. I cannot assign UCF s to inputs or outputs I think as there will be 129 inputs for the 64 bit additions between a and b and the carry and 65 outputs for the sum and carry out. How am I supposed to trigger the cores and not use UCF and check the working on Chip Scope using FPGA

    i want to see the out put of my adc on chip scope.I have clk2 as a divided clock which i am using as a clock to adc and i hav 10 bit signal as output.I am ot getting which signal to be connected to trigger.I have connected clk2_buf to clk port and my signal to trigger and set the data port same as trigger but i am not getting the output waveforn ..Can me please help me with this.

      May be problem with a clock. Or design is not functioning at all. Try simulating the design first.

    sir i have 2 problems in spartan 3e using xilinx 10.1
    1. I cant change the trigger width
    2. After press play button it’ll take more time to upload waveform and the sample %ge is at 0 only.

    for the below comment……………..
    It is not celecromng as clock signal,it is celecromng always high signal…….

      You cannot see the sampling clock in the chipscope. If you wish to see the clock signal itself, then, use the DCM to generate a clock signal which is twice (or even multiple) of the frequency of clock signal you want to observe. Then use this signal as a chipscope clock. You cannot measure time period from chipscope directly. Each time sample in the chipscope corresponds to one time period of the chipscope clock.

    I tried to see input clk in chip-scope pro wave window,but it is celecromng as clock signal.Why? In chip-scope pro we are not able to see input clock signal??
    If we want to measure the clock frequency of input signal,how to measure the frequency?
