Synthesis Training covers the aspect of converting the design in form of RTL into Technology mapped netlist. Synthesis is an algorithm intensive task consisting of many stages within it requiring various inputs in order to produce a functionally correct netlist. The main part of Synthesis Training consists of reading in the design, converting RTL to Boolean equations through elaboration, then converting the Boolean equations to Generic Mapped Cells and then technology mapped cells from library, setting constraints, optimizing the design, analyzing the results and saving the design database for Placement and Routing stage to take on. Candidates who are interested in exploring opportunities in Synthesis and Front-end STA can undergo this in-depth Synthesis training to get good understanding of RTL constructs, Gate level Netlist, Constraint Development, Latch based designs, pipe lining and re-timing, basic Scan stitching, Setup timing closure, Topography based logic re-structuring, Wire Load Models, Logical Equivalence Checks. Hierarchical Synthesis is another key feature covered in this Synthesis Training Cadence Implementation Suite for Synthesis (as RTL Compiler / Genus) would be used in this Synthesis Training program. Candidates would get hands on work on two full designs.
