But that is only just the start of what could be achieved according to CEO John Teegan who is now seeking additional application areas for the company's mixed-signal ICs and a possible IPO.
The company was founded in 2001 and is still privately held, but with unit shipments expected to be about 600 million units in 2016 it has clearly reached significant revenue and apparently with no direct competitors. That said at least one company, Anadigm Inc. (Mesa, Arizona) has been around for many years selling field programmable analog arrays.
Silego's offering is based on a one-time-programmable mixed-signal function array approach to analog, timing, some digital and power integration. Over the last several years the company has based its offering on a series of base die integrating a number of analog and digital functions. When put together with design software this allows users to develop custom circuits that are then characterized by way of on-die antifuse switches. Even though functions are analog they can be trimmed and checked physically for suitability in rapid order.
Silego and its customers get economies of scale through foundry partner TSMC and its 0.18-micron CMOS process used for the chips. Standard processing and packaging keeps part costs down in the 30¢ range, while prototyping can be iterated over a few days and production reached in weeks, the company states.
