Recent Tanner EDA Articles
Massimo Sivilotti, Ph.D of Tanner EDA showed me their 3D field solver in the HiPer PX extraction tool at DAC last week.
Notes
Tool Suites schematics, layout, SPICE simulation, DRC/LVS
- HiPer PX: 3D Field solver
o Layers, dielectrics,
o Finite element analysis
o Boundary element methods
o 2D mode for pattern matching
o PDK includes the info for PX extraction
o 3D viewer to see the IC Layout
o Offered for a few years now
o Extract: Devices, parasitic, interconnect
o Produces RC netlist (not L, not s-parameters), coupled C
o Take parasitic from PX extraction then view it in Schematic editor (S-Edit)
Swap out cell parasitics by changing the view
o Run times are more limited by your simulator, not the extraction
o Built-in netlist reduction algorithms (supply a frequency range), typically the reduced netlist is 10% the size of the original netlist
o Not a multi-core algorithm yet (T-Spice is multi-core for circuit simulation)
o Developed at TU Delft in Europe, licensed technology
o Runs on both PC and Linux (32 or 64bit)
o Comparable accuracy with Assura RX

- Dongles
- Commuter
- Time-based
- Rentals
- Even permanent licenses
L-Edit used for stacked die layout with IC and Mems
- Packaging techniques to locate all pads
3D Solid Modeler
- Used for MEMS Design have a solid modeler (air or dielectrics)
- Interfaces to Finite Element Analysis
- Optical example with mirror
Summary
Tanner EDA continues to offer affordable IC design tools, HiPer PX offers both 3D and 2.5D extraction depending on the accuracy that you need.
