Yeah, LSI had their own standard cell libraries up to around 180nm, then they didn't want to invest in fabs and started working with TSMC - beginning of the end

Yeah, LSI had their own standard cell libraries up to around 180nm, then they didn't want to invest in fabs and started working with TSMC - beginning of the end for them really. I signed off a couple chips on both sides of that transition. I worked in a group that did physical design, timing closure, test insertion, etc. I did a lot of layout automation in Avanti's tools; sometime after I left, it all went to Cadence I believe.
