Abstract
This talk will give an overview of automated standard cell and library synthesis and focus on the experiences made during the ongoing development of a cell generator. The core aspects consist of:
- Place & route inside the cell
- Transistor netlist generation & transistor sizing
- Cell characterization
- Open challenges
Software

Roadmap
- ✓ Place & route of single row cells
- ✓ Generate GDS
- [in progress] Generate LEF
- ✓ Timing characterization of combinatorial cells
- [in progress] Timing characterization of sequential cells
- Timing characterization of cells with tri-state output
- Timing characterization of cells with asynchronous inputs
- ✓ Generate synthesis liberty file (currently only for combinatorial cells)
- Capacitance extraction using a field solver (maybe FasterCap)
