First open source PDK where Google wasn t involved

Question

First open source PDK where Google wasn t involved <https github com IHP GmbH IHP Open PDK>

Amro Tork · Answer

That s a really great milestone

Keno Fischer · Answer

Neat looks like they re even planning a free MPW program

proppy · Answer

printed the cells included in the PDK here <https colab research google com gist proppy f63686b02309e287d4824098c728780e ihp pdk playground ipynb>

Tim Edwards · Answer

They ve got inductors

Tim Edwards · Answer

the open source PDK is not intended to be used for production at this moment That s a downer What exactly is meant by at this moment

Amro Tork · Answer

< Tim Edwards> This is an advanced RF process I know multiple people who used the closed source version of it I don t the PDK is ready for work

Amro Tork · Answer

It s just the start

proppy · Answer

They have a timeline hidden in their repo too

Tim Edwards · Answer

The big question here is what the price of a shuttle run is going to be This process has a lot of masks and a lot of processing steps SiGe is not known for being cheap

Keno Fischer · Answer

7 3k EUR mm^2 according to <https www ihp microelectronics com services research and prototyping service mpw prototyping service schedule price list>

Tim Edwards · Answer

Ouch The Caravel chip is 18 6mm^2 which comes to $145 000 US

Keno Fischer · Answer

Good value on the free shuttle then wink

Michael Strothjohann · Answer

< Keno Fischer> currently 6 2k EUR mm^2 respectively 5 1k EUR mm^2 for educational Institutions according to option MINI SIC Please take into account Ft Fmax=300 500GHz BTW GF charges comparable MPW prices for their 130nm SiGe BiCMOS technology

Michael Strothjohann · Answer

< Tim Edwards> I don t expect RiscV microcontroller cores in this technology but smaller predominantly analogue RF designs typically under 3mm^2 perhaps with small state machines for control i e a ring oscillator with few hundred GHz HF Filters

Michael Strothjohann · Answer

A little more background knowledge about IHP s SiGe technology Free download approx 110 MB <https www riverpublishers com research article details php book id=482>

Tim Edwards · Answer

< Michael Strothjohann> I only meant to be using the Caravel chip size as a reference for cost since I have a handle on what that much area is costing us for Sky130 and GF180MCU
