Cadence and Synopsys are the shovels of the chip boom, controlling 74% of the EDA software every chip design depends on. Customers essentially never leave: switching is costly and risky, software is half of chip design costs and lifetimes exceed 20 years. Revenue is 80-85% recurring with high-80s gross margins and net margins above 20%, and EDA is projected to grow 12-15% a year as end-product makers such as Tesla join chip firms as clients. x.com 

Cadence's IBD composite and EPS ratings of 90 support its standing as arguably the best in the 'making chips better' group after ASML. The screen estimates 2026 EPS growth of 18% and sales growth of 21%. Its chart is near a breakout after a long pullback. x.com 

Synopsys and Cadence are shorts while ASIC design houses Global Unichip and Alchip are longs, because hyperscalers are taking chip IP design in-house. Synopsys design IP income fell 48% in Q1 to $66.1M, yet EDA trades near 70x earnings after losing China. Megacap seat counts are flat to down as AI makes engineers 2-3x more productive; Google TPU, AWS Trainium and other ASICs sold Cadence no new seats. Global Unichip revenue is up 60%, and Alchip, working on Trainium, is the highest-beta long. … Show more

Synopsys and Cadence stand to benefit as headless software lets AI agents run design and simulation jobs without a UI, an end state that is pretty bullish for EDA companies. As simulation integrates physics, with Synopsys using Ansys tools tied into Nvidia's Omniverse, agent swarms could test 1,000 chip design permutations instead of two or three and sharply reduce physical testing. Getting there will take a while, and Synopsys will be a slow grower for a bit. x.com 

Synopsys and Cadence benefit as AI shifts from general-purpose to specific-purpose models, a transition moving unusually fast and a sign this is a continuation of the buildout rather than a new cycle. Synopsys and OpenAI signed a multi-year deal to build GPT-Synopsys, a model that runs Synopsys EDA tools for tasks like timing closure and verification, with shared revenue. Synopsys also announced a multi-year, $1B+ silicon IP agreement with Amazon, showing what EDA players' IP can be used for. … Show more

Synopsys looks expensive at $415.99, trading at 52 times cash earnings and 42 times next year's, against the roughly 30 times software companies usually get. That puts fair value at about $250.75 to $319.14, so buyers are paying about 30% over fair. The read is valuation levels only, based on reported earnings and revenue estimates, without fundamental work. x.com 

Cadence Design Systems is the tollbooth of chip design: nobody builds an AI processor without first paying for EDA software, a duopoly market. That shows in 88.9% gross margins and eight straight years of 16–21% EPS growth without a down year. It ranks first and is the highest-conviction name on the software map, with a 96.8 story score, 90.5 chart score and 93.6 composite; with both above 90, the argument is over. The stock sits about 2% from a fresh pivot. x.com  x.com 

"AI replaces EDA" is probably the wrong trade, because AI agents send more generated designs back through Cadence's and Synopsys's verification engines. Cadence's ChipStack RTL agent averaged 24% less area and 18% less power than raw model output in its own early tests, directional evidence, not a production benchmark. Cheap RTL still must be verified and signed off, so more designs can raise tool use per engineer. The bear case is pricing: if agents are bundled, customers keep the gains. x.com 

Synopsys and Cadence face a net competitive negative if large chip designers build custom verification tools in-house, taking share of the largest slice of the EDA workflow. The market will likely sell the incumbents as this gets digested. Offsetting that, faster time to market is becoming table stakes, raising both the value of agentic design tools and the cost of failure. @lokoyacap counters that nothing shows EDA being made unnecessary and that it supports pricier AI-enabled seats. x.com  … Show more

Arm's valuation carries an absurd premium for the architecture layer. It trades at 91.9x EV/sales, far above its historical range, as Wall Street prices it as the mandatory royalty tollbooth for every custom AI chip. EDA leaders Cadence, at 30.1x, and Synopsys, at 21.2x, trade near the low end of their historical bands, priced like mature utilities, as the market stacks almost all the scarcity premium into Arm. x.com
