hii all,i need to know how to perform eye diagram simulation in spectre and how to generate random i/p data ?thanx in advance.
Just run a transient simulation and then use the eyeDiagram function in the calculator to plot the eye diagram. Or with wavescsan/viva you can double-click on the x-axis and setup the eye diagram that way.There are various random sources in ahdlLib - e.g. rand_bit_streamRegards,Andrew.
THANKS A LOT !!!! that would certainly be helpful.
hi andrew, i've tried generating prbs data with rand_bit_stream as you said, but getting one problem.When i am increasing my simulation time the output from it is not achieving full voltage swing and not a square pulse anymore,but a triangular wave type..could you suggest some solution please.i would be grateful.
