The headline was very catchy and seemed impressive. After reading many times over I could read the fine print which brought about more clarity about the exact features. I didn't find it particulary high class engineering.
To be precise Speedview does not offer any Vdrop analysis per-se, but has been now able to overlay the voltage values at different points, on top of the existing layout.
The voltage values come from an external simulation. Speedview reads these values which need to specified in its own format. Then it annotates them on the layout geometries. Except a convenience of display there is hardly any information addition made by Speedview.
The role of Cooltime isn't really visible. Cooltime analyzes cell based designs only. The above feature of displaying Vdrop values has nothing to do with either cell base or full custom designs. There is no SPICE simulation done by either Columbus and Cooltime and is left to the user.
The claims made in the article seem to be exaggerated, and I request them to be reworded. Please change the headline to "Sequence OVERLAYS result of Vdrop analysis in the layout viewer"
