Parasitic Extraction Parasitics are 'devices' which are not intended but intrinsic to any physical representation of a circuit For instance: interconnect traces have Resistance Capacitance to their surrounding If you haven't read the CAD tool information page, READ THAT FIRST. The scaling down of geometrical dimensions introduces two-dimensional and even three-dimensional effects both in transistor behavior and in the parasitics. In this method, the PEX engine uses a look up table to calculate the parasitic R or C. This method is referred to as 2D or 2.5D extraction. Traditionally, LPE tools have offered two methods for capacitance derivation, with tradeoffs on these goals: a 3D field-solver algorithm The next step after DRC and LVS clean layout is the parasitic extraction that are not taken into account in schematic simulation Go to Assura --> Run QRC QRC (Assura)Parasitic Extraction Run Form will open. The proposed approach, unlike previous approaches available in the literature, estimates the parasitic capacitances and resistances from a simplified layout that includes the floorplan and a non-detailed routing, using an empirical-based method supported by the data from the technology design kit (TDK) files. Synopsys is a leading provider of high-quality, silicon-proven semiconductor IP solutions for SoC designs. These are transistor performance, and parasitic capacitances and resistances.
