US 12,769,446 B1 · Memory compaction to reduce emulation model size

Abstract

A method of performing hardware emulation of a circuit design includes, in part, receiving data from a first memory of the circuit design. The first memory has a depth of D1 words each having a width of W1 bits. The method further include determining the number of segments N of each word of the first memory defined by operation floor (W1/W=N), wherein W is a width of a memory primitive disposed in the hardware emulation system. The method further includes storing the N segments of each word of the first memory in first N locations of the memory primitive, and storing the remainder R of each word of the first memory defined by (W1−NW=R) in the memory primitive.

A method of performing hardware emulation of a circuit design, the method comprising:

receiving data from a first memory of the circuit design, wherein the first memory has a depth of D1 words each having a width of W1 bits;
determining a number of segments N of each word of the first memory defined by operation floor (W1/W=N), wherein W is a width of a memory primitive disposed in a hardware emulation system;
storing the N segments of each word of the first memory in first N addresses of the memory primitive;
and
storing a remainder R of each word of the first memory defined by (W1−NW=R) in a different one of second N addresses of the memory primitive.

A hardware emulation system comprising:

a memory storing instructions;
and
a processor, coupled with the memory and configured to execute the instructions, the instructions when executed causing the processor to emulate a circuit design, the instructions further causing the processor to:
receive data from a first memory of the circuit design, wherein the first memory has a depth of D words each having a width of W1 bits;
determine a number of segments N of each word of the first memory defined by operation floor (W1/W=N), wherein W is a width of a memory primitive disposed in the hardware emulation;
store the N segments of each word of the first memory in first N addresses of the memory primitive;
and
store K remainders R associated with K different words of the first memory and defined by (W1−NW=R) in a same address of the memory primitive, wherein R is an integer greater than or equal to 2.
