Over here at Cadence we were pondering the same question and
started by estimating the world wide verification community at 15,000
engineers. My colleague Joe Hupcey and I
arrived at that number by doing some calculations based on the number of
verification licenses we have, the EDAC numbers, and a bottom-up customer
analysis. We focused on engineers using
HVLs to separate the design and verification communities. Our next step was to objectively split that
community based on OVM and VMM usage and what we came up with supports Harry's methodology
10,000 of the 15,000 verification engineers are using the
OVM with SystemVerilog and eRM with e. The 10,000 splits into roughly 6000 on the OVM
(based on the number of engineers registered with the OVM World now) and 4000 eRM
users (based on the e users in the Team Specman blog, the Specman Yahoo group, and
the others below). We can combine these
to 10K because both eRM and OVM implement the same methodology - a methodology with
proven reuse for several years and across thousands of projects and the broadest, deepest VIP portfolio. If we assume the rest of the verification
engineers are using VMM and legacy Vera/RVM, then we roll-up to the same 2:1
ratio as Harry.
These tough economic times can make it hard to make resource
decisions. With 2:1 odds favoring the OVM, at least the verification
methodology decision is clear!
So where are you placing your bets?
