Analog Bits and SEMIFIVE is a Really Big Deal

Analog Bits and SEMIFIVE is a Really Big Deal
by Daniel Nenni on 03-28-2022 at 6:00 am

Given the recent acquisitions the ASIC business is coming full circle as a critical part of the fabless semiconductor ecosystem. The most recent one being the SEMIFIVE acquisition of IP industry stalworth Analog Bits. These two companies came to the industry from opposite directions which make them a perfect match, absolutely.

SemiFive Analog Bits SemiWiki

Analog Bits was founded in 1995 here in Silicon Valley the traditional way. Started by a group of engineers as a consulting company. In 2003 they pivoted to an IP company in concert with the foundries. This was a bootstrap operation (no debt) focused on customer success. I don’t recall my first engagement with Analog Bits but it was many years ago and for the last 4 years we have collaborated on SemiWiki.

Analog Bits is a critical supplier of leading edge mixed signal IP in the SoC, mobile, hyperscale, AI, and automotive communities. They started with PLLs, DLL, IO’s and memory IP, and have expanded to include SERDES, PVT, and POR. They are now serving customers down to 3nm which means intimate foundry relationships.

They have customers all over the world but more importantly Anaolg Bits is closely partnered with the top foundries: TSMC, Samsung, Globalfoundries, UMC, and had a recent announcement with Intel Foundry Services. As a foundry person myself I know the inside story here and let me tell you that it is an amazing achievement for a 50 person company.

SEMIFIVE took the opposite approach. After getting his PhD in Computer Architecture from MIT in 2012, Brandon Cho spent five years at Boston Consulting Group in Korea. In 2018 he joined SiFive in Korea and SEMIFIVE was spun out eight months later. Brandon and company have raised more than $100M in Korea thus far and now with a Silicon Valley based IP division (Analog Bits) expect them to raise more funds in California.

Here is a 2020 video explaining more about SEMIFIVE and what they do:

After the Analog Bits acquisition, SEMIFIVE has more than 350 employees and a solid base in North America. My prediction is SEMIFIVE will raise more money outside of Korea, do more acquisitions, and evolve into a multinational ASIC powerhouse.

They key to the ASIC business of course is IP and foundry relationships. SEMIFIVE has a close relationship with Samsung but does not currently work with TSMC. Analog Bits works closely with all foundries but has a very close relationship with TSMC. Seriously, it seemed like every time I was in Taiwan the Analog Bits team was there. To ensure these relationships continue unaffected by the acquisition Analog Bits will operate separately to remain foundry neutral.

Bottom line: To me this acquisition is another 1+1=3. SEMIFIVE gets a strong IP base in North America plus foundry and customer relationships that have been silicon proven for 20+ years. Analog Bits gets the ability to scale rapidly and increase the depth and breadth of their IP offering.

About SEMIFIVE
SEMIFIVE is the pioneer of platform based SoC design, working with customers to implement innovative ideas into custom silicon in the most efficient way.
