AC timing for logic module internal delays is determined
after place and route. The DirectTime Analyzer utility
displays actual timing parameters for circuit delays. ACT 1
devices are AC tested to a “binning” circuit specification.
The circuit consists of one input buffer + n logic modules +
one output buffer (n = 16 for A1010B; n = 28 for A1020B). The

logic modules are distributed along two sides of the device, as
inverting or non-inverting buffers. The modules are
connected through programmed antifuses with typical
capacitive loading.
