Comparing Simulation With and Without Crosstalk
–– Simulate
–– Create a separate density and contour plot for the new
data set.
A new, blank data display window opens, but we want to
re-use the previous one, so:
–– Close pcie_fext.dds.
–– Go to your previous pcie.dds data display window.
You can compare corresponding traces from two different
datasets by using their full names. These have the format:
dataset..trace (trace alone is just a shorthand for that item
in the default dataset).
–– Double click on the timing bathtub plot.
–– Select pcie_fext, then add TimingBathtub:
–– Similarly, add a VoltageBathtub plot, and a List plot of
Summary for pcie and pcie_fext.
Let’s see if we can push this design to a higher bit rate.
–– Overlaying two density and two contour traces on one
plot is possible but messy, so:
–– Create a separate density and contour plot for the new
data set.
Let’s see if we can push this design to a higher bit rate.
