  • Patent number: 11386250
    Abstract: A method of detecting a timing violation between a first sequential element and a second sequential element in a circuit design being emulated in a hardware emulation system includes, in part, determining a timing relationship between first and second clocks applied respectively to the first sequential element and the second sequential element, reconfiguring a combinational logic disposed between the first sequential element and the second sequential element as one or more buffers, setting a delay across the one or more buffers to one or more clock cycles of the hardware emulation system based on the timing relationship, reprogramming the first and second clocks in accordance with the delay, and detecting a timing violation if a change in an output of the first flip-flop is not stored in the second flip-flop within the delay.

  • Patent number: 11221864
    Abstract: An emulation host system can configure a reprogrammable hardware emulation system to emulate an electronic circuit design. The emulation host system can analyze the electronic circuit design for electronic circuits that are repetitive. The emulation host system can partition the electronic circuits onto a single partition. The emulation host system can map the single partition onto a single programmable logic element (PLE) of the reprogrammable hardware emulation system. The emulation host system can configure the reprogrammable hardware emulation system to emulate the electronic circuits using the single PLE.

  • Patent number: 10796048
    Abstract: The independent claims of this patent signify a concise description of embodiments. A method of performing hardware emulation of a circuit design is presented. The method includes partitioning a first portion of the circuit design to a first configurable logic chip of a hardware emulator, adding a selection circuit to the circuit design in the first configurable logic chip, and selecting one of a first signal or a second signal during a first clock cycle. The first signal and the second signal are used in the circuit design. The method further includes storing a first value associated with the selected signal during a second clock cycle, and sending the first value to an output pin of the first configurable logic chip during a third clock cycle. This Abstract is not intended to limit the scope of the claims.
