Fixed Capacitance Values for MX FPGAs (pF)
Test Circuitry and Silicon Explorer II Probe
MX devices contain probing circuitry that provides built-
in access to every node in a design, via the use of Silicon
Explorer II. Silicon Explorer II is an integrated hardware
and software solution that, in conjunction with the
Designer software, allow users to examine any of the
internal nets of the device while it is operating in a
prototyping or a production system. The user can probe
into an MX device without changing the placement and
routing of the design and without using any additional

verification time from several hours per cycle to a few
seconds.
Silicon Explorer II is used to control the MODE, DCLK, SDI
and SDO pins in MX devices to select the desired nets for
debugging. The user simply assigns the selected internal
nets in the Silicon Explorer II software to the PRA/PRB
output pins for observation. Probing functionality is
activated when the MODE pin is held HIGH.

Designer software, PRA and PRB pins are reserved as
dedicated outputs for probing. If PRA and PRB pins are
required as user I/Os to achieve successful layout and

override the option and place user I/Os on PRA and PRB
pins.
