Coming soon, you'll be able to integrate a core or cores with a wide range of peripherals (both analogue and digital) to design a complete custom SoC yourself, online: https://www.sifive.com/chip-designer

1. When would chip designer be released?
2. How long does it take for shuttle runs?

2 depends who is putting the shuttle mask set together, and how rapidly they can accumulate enough designs. Obviously the time to go through the fab is no different from any other wafers on the same process.

A release date for chip designer has not been announced.

It's essentially done and has been used to successfully replicate and tape out both the FE310 (320 MHz 32 bit microcontroller found in the HiFive1) and FU540 (1.5 GHz 4 + 1 core 64 bit Linux-capable found in the HiFive Unleashed) that were originally hand designed.

It's important to be reasonably sure that every design that the software allows a user to make will actually work :-)

As for shuttle runs ... SiFive goes directly to TSMC. There isn't any 3rd party accumulating things for a shuttle run. SiFive's Chip Designer automation feeds directly into TSMC's OIP VDE (Open Innovation Platform Virtual Design Environment).

Note that when TSMC announced this workflow in October, they chose to include quotes from Cadence, Synopsys, MIcrosoft, Arm, and SiFive: http://www.tsmc.com/tsmcdotcom/PRListingNewsAction.do?action=detail&language=E&newsid=THGOANTHTH

Thanks for the updates, so when you talk about SiFive Chip Designer does it do similar things like Cadence Virtuoso and other chip design tools?

brucehoult:
Very high level. You only pick what components you want: CPU cores, IP blocks. It's the system's/SiFive's responsibility to make sure it works. The user does nothing about layout, nothing about electrical characteristics. More like some of the high level drag-and-drop FPGA tools, except it's for SoCs.
