CXL hardware simulator

Create a software simulator for developers working with emerging Compute Express Link hardware. Accelerate driver and toolchain development.

Why now

New memory architectures like CXL need better tooling as adoption grows beyond early adopters.

Who for
Hardware/software engineers
Business model
Enterprise licensing
Effort
A few months

Hardware developers waste weeks debugging CXL implementations without good simulation tools.

Build an open-core simulator that models CXL.mem and CXL.cache protocols with visualization of memory coherence traffic.

Commercialize through paid enterprise features like detailed performance profiling and custom topology modeling.

Start with basic Type 1/2 device simulation before adding advanced features.

Risk: Niche market dominated by vendor tools - differentiate with better UX.
