ABSTRACT:
A system for measuring a timing skew between two digital signals may include a clock generator for generating a time measurement clock, and a pulse-to-digital converter for converting the timing skew into an equivalent digital coded value after correcting for internal logic delays. The system may further include a register bank for storing the digital coded values, and a controller for generating control signals and sequences for controlling the operation of the pulse-to-digital converter and the register bank.
