Pister http://www-bsac.eecs.berkeley.edu/cadtools/sugar Introduction: Software architecture: • Most MEMS designers use: • Most of the IC fabrication technology • Little of the simulation technology • Our goal: Be SPICE to the MEMS world • Challenges • Must be fast enough for design (not just verification) • Must handle coupled physical effects Netlist Analysis Results Solvers transient analysis uses mumps.net steady-state analysis param ox=0, oy =0, oz=0 System Assembly gap3dV2 p1 [b c D E] static analysis [l=100u w1=5u w2=5u gap=2u t1=0u t2=500u Device Models sensitivity analysiss V1=5 V2=12 ox=ox oy = oy oz=oz] Library MATLAB ™ Web User Interfaces M&MEMS: SUGAR on the Web SUGAR in action: • Hosted on Berkeley Millennium cluster • Requires only a web browser • Java required for 3D graphics • Used in Fall 2001 MEMS introduction course • Might use O(106) continuum finite elements • SUGAR system uses 2621 elements • Described with a few parameterized subnets Measurement feedback: Related work: • SPICE and related network simulators • ANSYS, ABAQUS, FEAP, other finite element codes • NODAS from CMU • Coventorware from Coventor Ongoing and future work: • More and better mechanical (and other) models • Contact detection and simulation • Exploiting sparsity and parallelism • Reduced-order modeling • Sensitivity analysis • Design synthesis and optimization • Improved numerical treatment of multi-scale multiphysics problems Figure courtesy R. Muller. KSJP15 • Optical measurement facilities provided by Muller’s Matisse group • Validate simulations by comparison to measured data • Use measurement to improve models
