µPDK : Journey Towards Adding new pdk to librelane

tools to look at :

1. openroad
2. librelane (dev branch)
mentioned to refer config.tcl and change the parameter !
will that be enough for any pdk ?

#pdk #librelane #openroad

µPDK [Notes]:

Given any pdk it needs to be structured in open_pdk format:
1. libs.ref : foundry data
2. libs.tech : tehnology and setup files

intital release of skywater pdk (without any struture ): https://github.com/google/skywater-pdk

ciel is package manager with prebuilds

we can also do custom build with open_pdk instruction -- I am going to try it now

Present Supported pdks :
skywater130 : A,B
global foundry : gf180mcu( what is mcu?)
ihp-sg13g2

what makes a pdk , pdk ??

Files format and required files for pdk

Openroad is independant of the pdks !!!

after routing the drc and signoff should be done

format required for this could be a hint

well again this is good for digital track , for analog flow changes ????

well got stuck with vendor eda tools , looking to support for librelane

aquiring more mana from nature :::)

Just got started again , starting with minimal patches for librelane

checking the Table Lookup of pdk
looks interesting
No good understanding of it

just found spice netlist with parasitics , need to open with some existing tools
