LunaPnR Phase 2

A versatile and fast new open-source place and route tool

Making a custom chip (ASIC) requires a vast arsenal of tools, to do synthesis, simulation, parasitic extraction and schematic entry. . LunaPnR aims to add a robust open-source automated place & route tool to the equation. Luna targets ASIC processes larger than 100nm, in which it can perform place & route, do clock-tree synthesis and timing verification. This allows to design e.g. mixed-signal (analogue + digital) chips used in sensors and IOT devices. LunaPnR integrates well with existing open-source tools, such as YosysHQ's Yosys (a logic synthesis tool) and KLayout (a manual ASIC layout tool), but also with commercial tools via industry standard file formats (LEF, DEF and GDS). A fully open toolchain allows for a complete chain-of-trust between the chip designer and the chip manufacturer, from digital design to GDS2 and back (via wafer inspection).

In this new project LunaPnR will implement and test detail routing algorithms, enhancing the quality of the parasitic extraction for use with the OpenSTA static timing analyzer, speed up the graphical user interface (so it can render very large design efficiently), implement and test the power structure/special net/padring placer & router, and integrate Logic Equivalence Check (LEC).
