The short version

  • Each has a real cost: Cadence Allegro cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.; SolidWorks the desktop application is Windows only, so Mac and Linux users need a virtual machine, a Windows workstation or the separate cloud xDesign product at 2,580 USD a year.
  • They diverge on capability: Cadence Allegro covers Constraint Manager, SolidWorks covers 3D solid modeling.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cadence Allegro

  • Cadence publishes no prices; resellers quote Allegro X from roughly $5,700 per seat per year on lease or about $18,000 perpetual with support, so the entry cost is several times a mainstream PCB tool and budget approval usually needs a business case.
  • The learning curve is steep and the interface carries decades of accumulated convention, so a designer coming from another tool needs weeks to become productive and formal training is effectively mandatory.
  • Capability is split across product tiers and add-ons, so the feature you assumed was in Allegro may be an extra SKU, and the quoted configuration deserves a line-by-line check against your actual requirements.
  • Perpetual licences still carry annual maintenance to stay on current releases, and lapsing maintenance means paying to rejoin later, so the perpetual option is only cheaper over a long horizon.
  • Library and part data management is a project in its own right; teams that treat it as an afterthought end up with inconsistent footprints that surface as manufacturing defects rather than design errors.

SolidWorks

  • The desktop application is Windows only, so Mac and Linux users need a virtual machine, a Windows workstation or the separate cloud xDesign product at 2,580 USD a year.
  • Perpetual licences are no longer sold through the vendor online store and come only through resellers, and a perpetual licence still needs a paid annual service contract to get upgrades and support, so buying once and paying nothing again is not really on offer.
  • Named-user subscription is per person rather than floating, so an organisation where several engineers each use CAD occasionally pays full seats for part-time use unless it negotiates otherwise.
  • History-based parametric modelling breaks noisily: a change high in the feature tree can cascade rebuild errors through an assembly, which is a real productivity cost compared with direct modelling tools.
  • Large assemblies stress single-threaded desktop performance, and teams routinely resort to configurations, simplified representations and expensive workstations rather than the software scaling on its own.
  • The Maker licence watermarks its files so they can only be opened on other Maker licences, which means hobby work cannot be carried into a commercial seat later without exporting to neutral formats and losing the feature history.

Questions people ask

Is Cadence Allegro or SolidWorks better?
Neither clearly leads. Cadence Allegro starts at On request and SolidWorks at $2820/year, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cadence Allegro or SolidWorks?
Cadence Allegro starts at On request and SolidWorks at $2820/year.
Does Cadence Allegro or SolidWorks run on more platforms?
Cadence Allegro runs on Windows, Linux. SolidWorks runs on Windows.
What is Cadence Allegro best used for?
Cadence Allegro is most often used for routing a ddr5 or high-speed serdes board where length matching and impedance rules must be enforced during layout, not checked afterwards, a rigid-flex design with multiple stackups that a general-purpose pcb tool cannot represent correctly, a team of pcb designers working concurrently on partitions of one large backplane, an organisation that already runs sigrity or clarity analysis and wants the layout constraints and the simulation to share one rule set. Of those, routing a ddr5 or high-speed serdes board where length matching and impedance rules must be enforced during layout, not checked afterwards and a rigid-flex design with multiple stackups that a general-purpose pcb tool cannot represent correctly are not what SolidWorks is typically brought in for.

Answered from the vendors’ own pages

Cadence Allegro: Can I still buy a perpetual Allegro licence?

Yes. Cadence channel partners quote both annual lease and perpetual licences for Allegro X, with perpetual starting around $18,000 including support. OrCAD X is more commonly sold as lease only.

SolidWorks: Can you still buy a SOLIDWORKS perpetual licence?

Not from the vendor online store, which sells only term subscriptions. Perpetual licences remain available through resellers, but they still require a paid annual subscription service contract for upgrades and support.

Cadence Allegro: How does Allegro differ from OrCAD?

OrCAD X is schematic capture and mainstream PCB layout; Allegro X is the high-speed implementation environment with the full constraint manager. They share a database, so moving up does not mean redrawing.

SolidWorks: How much does SOLIDWORKS cost per year?

The 3DS store lists Standard at 2,820 USD, Professional at 3,456 USD and Premium at 4,716 USD per named user per year, excluding local tax. Quarterly terms are 846, 1,038 and 1,416 USD.

Cadence Allegro: Is there a free or student version?

Cadence offers time-limited evaluation and academic programmes, but there is no free commercial tier.

SolidWorks: What is the difference between desktop SOLIDWORKS and the 3DEXPERIENCE cloud tiers?

The desktop application still does the modelling and installs locally on Windows. The 3DEXPERIENCE platform adds cloud storage, versioning, mark-up and shared review around it. SOLIDWORKS xDesign is the separate browser-native modeller at 2,580 USD a year, and it runs on Mac and Chromebook.

Cadence Allegro: Do I need Sigrity as well?

Only if you need signal or power integrity simulation. Allegro enforces constraints but does not simulate; Sigrity is a separate purchase.

SolidWorks: Is there a cheap version for hobbyists?

Yes. 3DEXPERIENCE SOLIDWORKS for Makers is 48 USD a year or 15 USD a month, limited to personal use with project sales under 2,000 USD a year, and its files are watermarked for Maker licences only.

SolidWorks: Does SOLIDWORKS run on a Mac?

Not natively. Use the browser-based xDesign, or run the desktop application in a Windows virtual machine.
