There were a number of announcements at DAC 2016 in Austin concerning SDC timing constraints verification and management. Real Intent announced the newest release of Meridian Constraints for sign-off of SoC designs. It features new and unique functional analysis, data-driven debug, and support for distributed design development.
In this blog, I want to cover the drivers for a new kind of Constraints verification tool.
Constraints Management today is clearly different from the pre-SOC and pre-IP eras. The design process is now truly distributed with much legacy and third-party IP in any new SOC design. This implies that the SDC creation process must go through the three steps of (a) aggregation from the component SDCs to an overall SoC-level SDC, (b) refinement of the SoC-level SDC, and (c) dis-aggregation of the SoC-level SDC into SDCs for the synthesis partitions. The key point here being that the synthesis-partition boundaries need not align with the logical boundaries of the component IPs. (more…)
