First of three parts: New verification challenges; the impact of more IP and integration; fitting within a power budget; what’s missing from the flow; performance vs. power.
While the industry has been talking about SoC power optimization for years, it is still in the early stages of shifting to a ‘Design for Power’ paradigm.
Modified platform approaches are beginning to take root across the industry. The question isn’t whether they will work, but when they will gain traction and what they will look like.
Advanced semiconductors are being applied in the automotive space in new ways all the time. Alongside this comes the low power challenge.
Consistent methodologies need to be developed, tools need to be power-aware, and all of this has to be connected into design flows—quickly.
Efforts are underway to improve the SoC design flow by bringing more electrical information forward.
Finding a happy medium between power and complexity is an ongoing challenge, and it’s only getting worse from here.
