Using an External
Power Supply

Connecting the Probe Pilot to the FPGA

Connecting Signals to the Target for Logic Analysis

Note: This section
does not apply to
Silicon Explorer Lite.
For those targets that lack the additional current reserves to
power the Probe Pilot, an external supply may be connected as
follows:
1. Connect the Probe Pilot ground and the power supply
ground to the target.
2. Connect the 5V lead of the supply to the 5V lead of the
Probe Pilot.
The Probe Pilot has a 22-pin (18 channels, a clock, VCC, GND,
and clock GND) and a 16-pin connector for FPGA debug, using
Actel's Action Probe circuitry. The Probe Pilot Lite only has the
16-pin connector.
Connect any of the Probe Pilot's 18 channel leads to the desired
target signals using standard test accessories. To sample
synchronously, connect the CLKIN lead to the target's clock
which must be a continuous signal. If the clock is greater than
20MHz, connect the CLK GND (twisted pair) to a ground point
near the CLK lead.
