Abstract
One, two, or three test pattern generation and encoding processes are performed for a circuit design to generate compressed test patterns for one or two input channel numbers. The one, two, or three test pattern generation and encoding processes are configured to minimize active input channels for each of the compressed test patterns. A test pattern count for each of a plurality of input channel numbers is determined based on the compressed test patterns for the one or two input channel numbers, a number of active input channels for each of the compressed test patterns, and an assumption of similar input data volumes for different numbers of input channels. The test pattern count information can be employed to determine an optimal number of input channels for a test decompressor.
