In an attempt to make sense of the overlap between Cadence Design Systems and Mentor Graphics, I put together a table of the main product lines with some best guesses about how the combined company would look at them should the takeover go through.
The colour coding means the product survives more or less as it is if it's green. Red does not necessarily mean cancellation but indicates where I think it is likely that it will be discontinued and any useful technology rolled into the survivor.
I've basically wimped out on a bunch of them - the ones all in that drab yellow-brown - and put a big don't know on the forthcoming tool Project Sydney as I'm not entirely sure how it overlaps with Catapult. I have put this together on the basis that Cadentor would be more likely to use the Calibre name for the bulk of the DFM tools in the same way that Mentor has even in cases where Cadence's inhouse product has a market share close to that of the Mentor tool.
The biggest question marks are over simulation products, both digital and mixed-signal, and the PCB tools. However, Mentor has demonstrated that is easier to support separate product lines than attempt to move customers to other tools. Cadentor might attempt to push OrCAD and PADS together, but to do the same with Allegro and Expedition could be troublesome.
With the emulators, I would expect Palladium to win out over Veloce simply on the basis that it is the incumbent. However, I would expect Cadentor to let Veloce live out its natural life. That may be the wrong assumption.
The interesting one is Encounter versus Olympus-SoC. I would expect Encounter to win within the company but Olympus has impressed at some chipmakers, so it would probably take some time to disappear under the Encounter name. If the takeover happens, it will be interesting to see whether Cadence considers NanoRoute or Olympus to be the better option.
Update 1: John Busco pointed out that I'd left out ASIC synthesis and static timing analysis. I've now updated the table to include them. Thanks John.
Update 2: Following a comment on other omissions, inFact, Platform Express and Seamless are now on the chart. Have a look at the comments below for the reasoning over how they are placed.
