Q: My cable does not have the TMS and the SDO pins. Why?
A: Your cable will not have the TMS and the SDO pin cables if it was
bought before the SX probing capability was introduced. To order
a new cable (Si-Ex-Ribbons), contact Actel customer service at
Customer.Service@actel.com.
Q: Is the Silicon Explorer displaying an incorrect signal?
A: Make sure that the signal is sampled at a sufficiently high
frequency. The sampling rate should be at least twice the
frequency of the fastest changing signal. The maximum frequency
at which the signal can be sampled is 100 MHz which limits the
frequency of the device to 50MHz. If a higher sampling frequency
is required than the PRA and the PRB pins can be connected to a
logic analyzer to view the signals.
Q: Why can't I find the net I wish to probe?
A: Silicon Explorer lists only the signals which are actually present on
the device. There is a possibility that the net which you wish to
probe has been optimized in Designer. Please check the list of the
nets combined in the combiner file (*.cob) which is exported from
Designer File>Export>Auxillary File with file type *.cob
