  • QuickCap for IC Extraction at DAC 2011

    John and Ralph from Magma gave me an update on QuickCap at DAC on Monday afternoon in their demo suite.

    - Digital Signoff, extraction
    - QCP: 2.5D RC for full ASIC designs
    - QuickCAP NX: 3D field solver
    - QCP:

    Demo 1.5 million instance design, 1.59 million nets, fully P&R, three libraries
    - QCP: Gate Level (Star RC competitor)
    - QuickCapNX: 3D field solver (Raphael competitor)
    - QCP TX: Transistor Level (RC XT competitor)
    - QCP
    o 10X faster than Star RC
    o 20X faster with multi-corner extraction
    o Accuracy: +-2% of QuickCap NX
    o TSMC qualified at 28nm
    o Inputs: LEF, DEF, GDS II
    o Scaling: can add multiple corners using only 20% run time, can be distributed across more boxes
    o Capacity: 50M instance designs, memory efficiency
    o Accuracy (vs Star RC)
    o Example: TSMC 40nm, 38K nets
    o 1 corner at 5 hrs, 12 corners at 8.4 hours (27X faster than Star RC), using 3.3GHZ CPU, 148GB and 12 CPUs
    o One license per four cores (after that add a multi-core to add up to 32 cores)
    o 16 Synopsys licenses for a runtime of 60 minutes, vs 2 licenses in 34 minutes
    o the run time, the HW, 1/8 the licenses (compared to Synopsys with 80% market share)
    o 3D on demand (add QuickCap NX), name the nets you want best accuracy on
    - Tekton a STA tool
    o Reads SPEFS
    o Fast STA in minutes
    o Concurrent MM/MC
    o Accurate with SPICE integration
    - Old flow
    o Implement, output a GDS II
    o Extract, output SPEF
    o STA
    - New Flow
    o Implement
    o QCP and Tekton
    - QuickCap NX: Industry Golden 3D Field Solver
    o Same run time independent on
    o Three methods:
     Finite Element (Slowest)
     Boundary Integral (Slow, what Mentor 3D XACT uses)
     QuickCap (Fastest)
    o Field-solver accuracy (within 1% of Silicon)
    o Good for library characterization, custom, analog
    o Flow Inputs: ITF or iRCS from foundary, GDS II layout
    o Industry standard solver at IDMs, Foundries
    o Edge effects
    o Qualified by TSMC
    - QCP TX transistor level extraction
    o Millions of transistor capacity
    o To be released in 6 months
    o For: Custom design, memory, AMS
    o CCI Calibre Connectivity Interface, stress parameters, well proximity
    - QCP Demo
    o 18 million nets extracted per hour on 8 threads

    Star RC (Synopsys) has plenty of competition from Magma, Mentor and Cadence for IC extraction. I also learned more about 3D Field Solvers on Tuesday at the Pavilion Panel session.
