Operator Precedence Hardware

MediumLogic CircuitAnalyze

Hardware synthesis tools map logical expressions directly to gate-level topologies where operator evaluation order dictates the resulting critical path.

The snippet below contains two continuous assignments for outputs Y_chain and Y_tree using 8-bit inputs A, B, C, and D.

assign Y_chain = A + B + C + D; assign Y_tree = (A + B) + (C + D);

Analyze the default evaluation order and determine the resulting hardware depth for each expression.

Constraints

  • Assume basic synthesis without advanced datapath optimization or automatic tree balancing.
  • All inputs arrive simultaneously at time zero.
  • All operators map to basic 2-input hardware blocks.
