Loop optimization for implementing circuit designs in hardware

A system, comprising:

• a memory configured to store program code;
• and
• a processor coupled to the memory, wherein the processor, in response to executing the program code, is configured to initiate operations for implementing a circuit design including:
• determining a chain of a plurality of loop elements of a circuit design, wherein each loop element includes a bit select node configured to perform a bit assignment operation and a corresponding address calculation node, wherein the address calculation nodes use a common variable to calculate a starting bit location provided to the corresponding bit select node;
• in response to the determining, replicating the chain resulting in one chain for each value of the common variable and transforming each chain into a plurality of wires;
• inserting a multiplexer into the circuit design;
• and
• coupling the plurality of wires for each chain to inputs of the multiplexer, wherein the common variable is provided to the multiplexer as a select signal.

A computer program product comprising a computer readable storage medium having program code stored thereon, the program code executable by a processor to perform operations for implementing a circuit design, comprising:

• determining a chain of a plurality of loop elements of a circuit design, wherein each loop element includes a bit select node configured to perform a bit assignment operation and a corresponding address calculation node, wherein the address calculation nodes use a common variable to calculate a starting bit location provided to the corresponding bit select node;
• in response to the determining, replicating the chain resulting in one chain for each value of the common variable and transforming each chain into a plurality of wires;
• inserting a multiplexer into the circuit design;
• and
• coupling the plurality of wires for each chain to inputs of the multiplexer, wherein the common variable is provided to the multiplexer as a select signal.
