OMC allocator
Outputs of the 16 OMCs can be routed to a combination of pins on Port A (80-pin devices
only), Port B, or Port C as shown in
after specifying pin numbers in PSDsoft Express. Routing can occur on a bit-by-bit basis,
spitting OMC assignment between the ports. However, one OMC can be routed to one only
port pin, not both ports.
Product term allocator
Each OMC has a Product Term Allocator as shown in
Express uses PT Allocators to give and take product terms to and from other OMCs to fit a
logic design into the available silicon resources. This happens automatically in PSDsoft
Express, but understanding how PT allocation works will help if the logic design does not
“fit”, in which case the user may try selecting a different pin or different OMC for the logic
where more product terms may be available. The following list summarizes how product
terms are allocated to each OMC, as shown in
