Abstract
Integrated circuits with dynamic pin routing capabilities are provided. An integrated circuit may include circuitry under test and a dynamic signal routing controller. The dynamic signal routing controller may include multiplexers, a test register, and a signal select register. The circuitry under test may be connected to internal test lines that receive static test signals and dynamic test signals. The internal test lines that receive static test signals may be selectively routed to the test register (e.g., test registers store static test signals) while the internal test lines that receive dynamic test signals may be selectively routed to test pins (e.g., dynamic test signals are driven through the test pins). Each multiplexer may have a given input that is connected to the test register and additional inputs that are connected to the test pins. The signal select register stores control bits that configure the routing performed by each multiplexer.
