Field-net for placement evaluation

A system for determining a function for a QoR for a circuit design, the system comprising:

• a memory;
• and
• a processor communicatively coupled to the memory, the processor configured to:
• receive a first circuit design comprising a first node, a second node, and a connection between the first node and the second node, wherein the first node, the second node, and the connection occupy a portion of a design space;
• place an array of points within the design space;
• sample first field values of the first circuit design at each point of the array of points;
• determine a first sampled function based on the first field values;
• move the array of points within the design space;
• after moving the array of points, sample second field values of the first circuit design at each point of the array of points;
• determine a second sampled function based on the second field values;
• and
• determine a function based on the first sampled function and the second sampled function, wherein the function produces a QoR for the first circuit design.

A non-transitory computer readable medium storing instructions for determining a function for a QoR of a circuit design, wherein the instructions, when executed by a processor, cause the processor to:

• sample first field values of the circuit design at each point of an array of points placed in a design space, wherein a portion of the design space is occupied by the circuit design;
• determine a first sampled function based on the first field values;
• after producing the first sampled function, move the array of points within the design space;
• after moving the array of points, sample second field values of the circuit design at each point of the array of points;
• determine a second sampled function based on the second field values;
• and
• determine the function for the QoR based on the first sampled function and the second sampled function.
