The Magma deal also brought new customers to test the tool on. Haider added:
Having the collaborative access to customers is a big part of it as it’s just not possible to build a system like this in isolation. You need to have a good range of designs so that the new technology can be tested out. It’s been many years in the works.
Part of this change is a new incremental timer that’s multi-threaded-friendly.
The clock tree is completely rebuilt to support more global optimization, he says. The traditional approach is to optimize different paths independently and the optimization is through the delay and one branch relative to the other.
"We get pretty good results with that flow, and this powers todays chips, but it's expensive and the paths can be very, very large," Haider said. "So the new approach is more global with a network solver that looks at the tree overall and computes the delay."
Haider expects to see 10-15 design starts this year with the tool, including the existing early access customers. "We have seven or so active designs in different stages of tapeout using the partial systems," he said. "We have some customers who have done a partition with the early software and they are looking to proliferate to other designs so I think in 2015 we will blow past the 20-30 range."
