Analog/Mixed-Signal Library

OSHW component library for ASIC design

One of the gaps in the open chip toolchain is a libre-licensed analog/mixed-signal library. Having access to such a library contributes to having a fully open ASIC design infrastructure through which secure and trustworthy open hardware can subsequently be built.

This project is trying to fill that void. The first part of the project consists of enhancing and stabilising the underlying PDKMaster project, and allow it to facilitate programmatic co-generation of circuit and layout with integrated support for circuit simulation. This should make resulting circuits DRC and LVS clean by design. Second part of the bootstrapping effort is then to implement a set of scalable analog/mixed-signal blocks which can be integrated into PDKMaster. The initial set will consist of the following 4 core blocks: a voltage reference, a PLL (phase-locked loop), a low frequency, low accuracy ADC and a low frequency, low accuracy DAC.

The overall focus is on proving the overall suitability of the PDKMaster framework, rather than on the complexity and difficulty of the individual analog/mixed-signal blocks which are to be added. Thanks to proper documentation and examples, users can start expanding the available building blocks by adding their own contributions.
