Lambdalib is a modular hardware abstraction library which decouples design from the underlying manufacturing target. Lambdalib defines a set of generic functions that get resolved during the target technology mapping stage.
Lambdalib includes the following hardware categories:
| Category | Description |
|---|---|
| stdlib | Standard cells (inv, nand, ff, ...) |
| auxlib | Aux cells can consist of multiple standard cells or physical only cells |
| ramlib | Memory (single port, dual port, fifo, ...) |
| iolib | IO cells (bidir, vdd, clamp,...) |
| padring | Padring generator |
| vectorlib | Vectorized library (mux, isolation) |
| fpgalib | FPGA cells (lut4, ble, clb) |
The Lambdapdk repository demonstrates implementation of the Lambdalib interfaces across a number of open source process technologies.
Lambdalib has been successfully used in multiple tapeouts using SiliconCompiler.
