Bit Reversal Synthesis
Hardware description languages often use loops to express repetitive operations, but synthesis tools map these constructs directly to physical wires and gates.
The provided RTL report shows a parameterizable module that takes an N-bit input bus in_bus and assigns it to an output bus out_bus. Inside an always block, a for loop iterates through the bus, assigning the MSB of in_bus to the LSB of out_bus, and so on, completely reversing the bit order. A Yosys synthesis stat report is generated for this module.
Analyze the synthesis statistics for this bit reversal operation. Determine the hardware cost, logical delay, and routing implications of the generated netlist.
Constraints
- The bus width
Nis a parameter greater than 1. - The synthesis targets a generic standard cell library.
- The RTL uses a purely combinational
alwaysblock.

Solve this problem
Place the gates, wire them up and watch the signals settle. Every submission runs on the same simulation engine that grades it.
