Gongwei Wang's updates
My name is Gongwei and I will be working on the EDA device modeling this semester
Weekly Update #0
Created GitBook page.
Weekly Update #1
What was accomplished:
Did preliminary research into Skywater SKY130 PDK, OpenLane, SPICE modeling software.
Collected and read documentation on Open-source tools available for EDA and PDKs
SPICE parameter list: https://www.seas.upenn.edu/~jan/spice/spice.MOSparamlist.html
Roadblocks:
No roadblocks at the moment.
Plans for the week:
Extracting various preliminary MOSFET parameters for SPICE simulation (such as g_m, lambda, Vth) from some I-V, C-V graphs plotted in the previous semester from Icey.
Weekly Update #2
What was accomplished:
Communicated with Wentao for his NMOS and SRAM I-V data from the previous semester.
Plotted and analyzed preliminary MOSFET parameters for Vth.
Confirmed that we need to collect more data due to the limitations of the existing I-V data points.
Wrote up a plan of equations and different methods of extracting Vth, and lambda.
Roadblocks:
No roadblocks at the moment.
Plans for the week:
Collaborate with Ying to: classify accuracy levels for device parameter extraction and attempt extraction on existing chip 613
Collect more data on Chip 613, most likely using the probe station under a larger range of Vds and Vgs
Continue writeup on the parameter extraction doc of equations and different methods of extracting gm, lambda (Vth is ok).
