Abstract
A logic block in a product-term based programmable device comprising a first logic gate, a second logic gate, a macrocell and a multiplexer. The first logic gate may be configured to generate a first output in response to a logical combination of a first number of product terms. The second logic gate may be configured to generate a second output in response to a logical combination of a second number of product terms. The macrocell may be configured to generate a third output in response to the second output. The multiplexer may be configured to select an output of the device in response to (i) the first output or (ii) the third output. The first number of product terms may be a subset of the second number of product terms.
