I believe main NRE cost was the design of the substrate but this could be shared if we standardize the bump array on silicon.

"I believe under our circumstances we should likely be free to do a modular bond-out substrate that can hold a full die or a half-die; depending on precision and need for gaps and how wide the dice line is (I fear it's not actually a positive width, if we're doing guided crystal fracture to split the substrate bulk), it could even be feasible to co-package two half dies in the space of a full die (I think some here have been working on chiplet/transputer like arrangements).\n\nI have to focus on the SerDes getting onto IHP SG13CMOS5L now though; reason being that silicon being sponsored and that porcess being not unlikely so much faster that I could pull off 25G with the exact same analog frontend topology that would do 10G on gf180mcuD.\n\nAnd hopefully we can have a silicon-tested/SPICE-extraction-calibrated thin oxide SCL on gf180mcuD by the time the finalization of data path widths happens for the SerDes instance that I hope to get onto Run4.\n\nBecause I do quite want to have \"reasonable\" confidence in the SCL part not being the reason the SerDes fails to reach protocol speeds, and especially on the larger gf180mcuD I feel like overly wide datapaths on the SCL side would have substantial potential for dragging it all towards \"large area need, PA not even included\".", "author": { "id": "262706220073222144", "name": "namibj", "discriminator":

any substantial design effort into any fancy FIR, beyond-trivial pad capacitance matching/compensation, and ESPECIALLY any RX design, at least anything beyond trying to vaguely understand sensitivity time window for a strong arm latch implementation on that very process (as that strongly guides planning of how small of an UI to aim for in the RX, and it's area requirements gonna give a substantial
