Pipelined Multiplier Area
High-performance DSP blocks rely on pipelined multipliers to meet aggressive timing closures in modern FPGAs and ASICs.
The synthesis tool evaluates an RTL design containing a 16-bit multiplier. In the baseline design, the inputs A and B are multiplied to produce a 32-bit output P in a single clock cycle. In the modified design, two pipeline registers are inserted directly into the multiplication logic, splitting the operation into three stages.
Analyze the synthesis behavior for both designs. Determine the impact of pipelining on the inferred cell primitives, the critical path delay, and the overall area utilization.
Constraints
- Analyze the behavior of Yosys when synthesizing pipelined arithmetic versus single-cycle arithmetic.
- Assume a standard cell library where flip-flops have a fixed area penalty and setup time requirement.
- Assume the multiplier is implemented using standard logic gates, not dedicated hard IP macros.
