Native product terms come from the AND-OR Array. Each OMC may borrow product terms
only from certain other OMCs, if they are not in use. Product term allocation does not add
any propagation delay to the logic. The fitter report generated by PSDsoft Express will show
any PT allocation that has occurred.
If an equation requires more product terms than are available to it through PT allocation,
then “external” product terms are required, which consumes other OMCs. This is called
product term expansion and also happens automatically in PSDsoft Express as needed. PT
expansion causes additional propagation delay because an additional OMC is consumed by
the expansion process and its output is rerouted (or fed back) into the AND-OR array. The
user can examine the fitter report generated by PSDsoft Express to see resulting PT
allocation and PT expansion (expansion will have signal names, such as ‘*.fb_0’ or ‘*.fb_1’).
PSDsoft Express will always try to fit the logic design first by using PT allocation, and if that
is not sufficient then PSDsoft Express will use PT expansion.
Product term expansion may occur in the DPLD for complex chip select equations for Flash
memory sectors and for SRAM, but this is a rare occurence. If PSDsoft Express does use
PT expansion in the DPLD, it results in an approximate 15ns additional propagation delay for
that chip select signal, which gives 15ns less time for the memory to respond. Be aware of
this and consider adding a wait state to the 8032 bus access (using the SFR named,
BUSCON), or lower the 8032 clock frequency to avoid problems with memory access time.
