Synopsys, Inc. (NASDAQ:SNPS) and Cadence Design Systems, Inc. (NASDAQ:CDNS) between them supply almost all of the software used to design advanced chips.
Both have fallen over the past twelve months even as the chips they help create have driven the market higher. That is the puzzle worth examining, because their share of the market has not visibly changed.
Synopsys Bought Growth and Took on Debt to Get It:
Synopsys is the larger business, with $9.42 billion of revenue against Cadence’s $5.84 billion, and it is growing faster after acquiring Ansys.
Revenue rose 42.4% in the most recent quarter, and Synopsys has said most of the increase came from the Ansys acquisition.
The cost shows up in two places. Operating margin sits at 14.52%, well below what this industry normally produces, and total debt reached $10.84 billion. Return on equity has fallen to 3.66% as a result, since the acquisition enlarged the equity base before delivering the earnings to match.

Cadence Grew Without Buying Anything and Costs More for It:
Cadence grew revenue 24.2% last quarter without an acquisition on the scale of Ansys. Acquired revenue arrives with integration risk attached, and organic revenue does not.
Its economics are also better. Operating margin runs at 28.58%, nearly double Synopsys, and it carries $2.65 billion of debt against Synopsys’s $10.84 billion.
Investors pay for that on the measures that look forward. Cadence changes hands at more than 15 times revenue against roughly 8.5 times for Synopsys.
On trailing earnings, the relationship reverses. Synopsys is the more expensive of the two, at 73 times against 65, because the Ansys charges have pushed its current profit down.
What both share is the position itself. Chip designers cannot switch these tools easily. The designs, the component libraries, and the engineers are all built around one vendor, and moving costs far more than the software ever does.
That lock-in is why the duopoly has lasted. A chip company changing design software would have to revalidate work it has already proved and retrain staff who took years to become fluent. It would also accept delay, and delay is expensive in this industry.
Most of the revenue at both companies is renewal rather than new business, which is a far easier position to hold.
Artificial intelligence has, if anything, strengthened both positions. The companies designing AI accelerators are among the best-funded buyers in the industry, and both vendors have pointed to that demand on recent calls.
Neither company is fighting to keep its customers. They are competing on what investors will pay for that position.
Conclusion:
Cadence is the better business by almost every operating measure. It earns roughly double the margin and carries a fraction of the debt, and it grew without buying anything. Investors have noticed, which is why it costs more on sales and on forward earnings, even though Synopsys looks dearer on trailing profit. The choice therefore reduces to whether Ansys works. If those profits arrive, Synopsys is the cheaper route into the same duopoly. If they do not, the lower multiple reflects the debt rather than an opportunity.
