Abstract
A method of storing data during verification of a circuit design by a hardware emulation system, includes, in part, receiving, once in every N emulation clock cycles, P sets of register data each set including M register bits associated with the circuit design. The M register bits of each set in P shift registers are stored during M cycles of a capture clock. The stored bits are shifted out during M*P cycles of the capture clock, where (M+1)*P is less than or equal to N.

A method of storing data during verification of a circuit design by a hardware emulation system, the method comprising:
- receiving, once in every N emulation clock cycles, P sets of register data each set comprising M register bits associated with the circuit design;
- storing the M register bits of each set in P shift registers during M cycles of a capture clock;
- and
- shifting out the stored bits during M*P cycles of the capture clock, wherein (M+1)*P is less than or equal to N.
A non-transitory computer readable medium comprising stored instructions, which when executed by a processor, cause the processor to:
- receive, once in every N emulation clock cycles, P sets of register data each set comprising M register bits associated with the circuit design;
- store the M register bits of each set in P shift registers during M cycles of a capture clock;
- and
- shift out the stored bits during M*P cycles of the capture clock, wherein (M+1)*P is less than or equal to N.
A circuit comprising P shift registers each configured to receive, once in every N emulation clock cycles, P sets of register data each set comprising M register bits, each of the P shift registers further configured to store the M register bits during M cycles of a capture clock and shift out the stored bits during M*P cycles of the capture clock, wherein (M+1)*P is less than or equal to N.
