184.108.40.206. Pipelining at Variable Latency Locations
The current version of the Intel® Quartus® Prime software includes new features to help improve timing performance for design paths that are insensitive to additional latency. The Hyper-Retimer can now automatically add pipeline stages on false paths that you tag as latency-insensitive, and also insert the appropriate number of pipeline stages at the registers you specify. The Hyper-Retimer retimes the added registers into timing-critical parts of the design. The number of pipeline stages that the Hyper-Retimer adds can change for each compilation, or any time you change the design.
- If you do not specify latency-insensitive false paths or use autopipelining, the Hyper-Retimer output netlist is cycle-equivalent to your RTL.
- If you specify latency-insensitive false paths or use autopipelining, the Hyper-Retimer output netlist is not cycle-equivalent to your RTL. Therefore, your simulation and verification environments must accommodate variations in the circuit latency to use these techniques.
