At DAC this year I had a lot of fun doing a live experiment to demonstrate some of the benefits and issues with concurrent design flows. I was at the Cadence Theatre doing a presentation called ‘Controlling the costs of SoC integration‘ and I decided to make the presentation more interactive by creating a design team and seeing some of the effects of getting this team to work concurrently. We demonstrated how a little ‘twist’ caused a big upset for to team deliveries!
The topic I introduced first was how system design flows are now highly concurrent. In the production of a system within a very tight timescale, it would be normal to have architecture definition, software development, virtual prototype development, RTL design and verification all happening at the same time, be it IP, sub-system or SoC level design. I represented this as a set of rotating, interacting cogs.
