Description
The XC3100A is a performance-optimized relative of the
XC3000 and XC3000A families. While all families are
footprint compatible, XC3100A familiy extends the system
performance beyond 80 MHz.
The XC3100A familiy follows the XC4000 speed-grade
nomenclature, indicating device performance with a num-
ber that is based on the internal logic-block delay, in ns.
The XC3100A family offers the following enhancements
over the popular XC3100 family.
The XC3100A family has additional interconnect resources
to drive the I-inputs of TBUFs driving horizontal Longlines.
The CLB Clock Enable input can be driven from a second
vertical Longline. These two additions result in more
efficient and faster designs when horizontal Longlines are
used for data bussing.
During configuration, the XC3100A devices check the
bitstream format for stop bits in the appropriate positions.
Any error terminates the configuration and pulls INIT Low.
When the configuration process is finished and the device
starts up in user mode, the first activation of the outputs is
automatically slew-rate limited. This feature, called Soft
Startup, avoids the potential ground bounce when all
outputs are turned on simultaneously. After start-up, the
slew rate of the individual outputs is, as in all XC3000
families, determined by the individual configuration option.
The XC3100A family is a superset of the XC3000 families.
Any bitstream used to configure an XC3000, XC3000A,
XC3000L or XC3100 device, will configure the same-size
XC3100A device exactly the same way.

CLB Switching Characteristic Guidelines (continued)
Testing of the switching parameters is modeled after testing methods specified by MIL-M-38510/605. All devices are 100%
functionally tested. Since many internal timing parameters cannot be measured directly, they are derived from benchmark timing
patterns. The following guidelines reflect worst-case values over the recommended operating conditions. For more detailed, more
precise, and more up-to-date timing information, use the values provided by the XACT timing calculator and used in the simulator.
