PIA Signals
While the routing delays of channel-based routing schemes in masked or
FPGAs are cumulative, variable, and path-dependent, the MAX 7000A
PIA has a predictable delay. The PIA makes a design’s timing
performance easy to predict.
I/O Control Blocks
The I/O control block allows each I/O pin to be individually configured
for input, output, or bidirectional operation. All I/O pins have a tri-state
buffer that is individually controlled by one of the global output enable
signals or directly connected to ground or V
.
Figure 6
shows the I/O
CC
control block for MAX 7000A devices. The I/O control block has 6 or
10 global output enable signals that are driven by the true or complement
of two output enable signals, a subset of the I/O pins, or a subset of the
I/O macrocells.
