SX-A Probe Circuit Control Pins
SX-A devices contain internal probing circuitry that
provides built-in access to every node in a design,
enabling 100% real-time observation and analysis of a
device's internal logic nodes without design iteration.
The probe circuitry is accessed by Silicon Explorer II, an
easy to use, integrated verification and logic analysis tool
that can sample data at 100 MHz (asynchronous) or
66 MHz (synchronous). Silicon Explorer II attaches to a
PC’s standard COM port, turning the PC into a fully
functional 18-channel logic analyzer. Silicon Explorer II
allows designers to complete the design verification
process at their desks and reduces verification time from
several hours per cycle to a few seconds.
The Silicon Explorer II tool uses the boundary-scan ports
(TDI, TCK, TMS, and TDO) to select the desired nets for
verification. The selected internal nets are assigned to the
PRA/PRB pins for observation. Figure 1-13 illustrates the
interconnection between Silicon Explorer II and the FPGA
to perform in-circuit verification.
Design Considerations
In order to preserve device probing capabilities, users
should avoid using the TDI, TCK, TDO, PRA, and PRB pins
as input or bidirectional ports. Since these pins are active
during probing, critical input signals through these pins
are not available. In addition, the security fuse must not
be programmed to preserve probing capabilities. Actel
recommends that you use a 70
Ω series termination
resistor on every probe connector (TDI, TCK, TMS, TDO,
PRA, PRB). The 70
Ω series termination is used to prevent
data
transmission
corruption
during
probing
and
reading back the checksum.
