When Galaxies CollideOctober 19, 2018
Although referring simply to two galaxies isn’t quite fair: one, Synopsys, is perhaps more of a galaxy cluster to Coventor’s galaxy.
Once upon a time, it was the earliest category of tools in the lifetime of a semiconductor process, used for creating, with the help of wafer data, SPICE decks and PDKs that provide higher-level abstraction for use by circuit designers.
and simulates how structures will look after those process steps are applied.
TCAD (Synopsys) has been about deriving electricals from structure.
Process simulation (Coventor) has been about deriving structure from process recipes.
As we noted last year , Silvaco is going through something of a transition, but they say that they’re still doing a reasonable TCAD business (although their development focus for the moment is more on design tools than TCAD tools, since they see more business opportunity there).
And TCAD can’t do that early device evaluation; that’s the job for a new set of tools that have become necessary over the last several years.
And that’s what Synopsys is changing .
To be clear, they’re not coming out with their own new ab initio tools; they’re providing an interface to the existing tools so that the results can be imported for further work.
Printability assessment (without wafers) has been possible for the last few years, but Process Explorer provides a faster way to simulate the other basic steps, operating about 1000 times faster than their full-on Sentaurus simulation tool.
