Lambdalib is a modular hardware abstraction layer that helps decouple hardware design from manufacturing technology and proprietary IP. Lambdalib defines a set of technology independent generic functions that can be directly instantiated within the design. Technology specific implementations can be linked in at compile time.
Lambdalib includes the following hardware categories:
| Category | Description |
|---|---|
| stdlib | Standard cells (inv, nand, ff, ...) |
| ramlib | Memory (single port, dual port, fifo, ...) |
| iolib | IO cells (bidir, vdd, clamp,...) |
| padring | Padring generator |
| vectorlib | Vectorized helper library (mux, isolation) |
| syslib | Vendor agnostic peripheral interface(uart, i2c,...) |
The Lambdapdk repository demonstrates implementation of the Lambdalib interfaces across a number of open source process technologies.
Lambdalib has successfully used in multiple tapeouts using SiliconCompiler.
