Synopsys

One half of the EDA duopoly that every serious chip is designed in. Picks and shovels for silicon.

Hold

Ten-year thesis

You cannot tape out a leading-edge chip without Synopsys or Cadence. Licenses are sticky, engineers are trained on one stack, and verification IP accumulates. Ansys (simulation) extends the franchise into physics. A ten-year hold is a bet that chip design complexity only goes up — AI chips, automotive, custom silicon — and that the duopoly holds. Quiet, expensive, and much closer to a Buffett industrial than the market treats it.

The moat

Duopoly, workflow lock-in, and the exploding verification burden at each node. Intangible process knowledge. Scale in R&D that a third engine cannot fund.

Switching costs94

Pain, risk, or retraining required to leave.

Network effects50

The product gets better as more people use it.

Intangibles & IP92

Patents, data, licenses, process knowledge, regulation.

Scale advantage80

Fixed costs spread over a volume rivals cannot match.

Cost advantage70

Structural ability to be the low-cost producer.

Brand72

Pricing power from trust, habit, or identity.

Tech overlay

EDA is the definition of a tech moat a non-tech investor skips because the acronyms are scary. Learn them once. The switching-cost structure is then obvious.

What can break it

Cadence taking relative share
Export controls on EDA to China
Ansys integration risk

Owner earnings yield 2.1%. Yield is judged against quality, not against a single hurdle — a fortress can be fairly priced at a lower yield than a fragile name.
