Terms of Service

1. Acceptance of Terms

By accessing or using OpenCores (the “Service”), operated by OpenCores (“we,” “our,” or “us”), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

2. Account Registration

You must create an account and select a subscription plan to use the Service. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. You must provide accurate information and be at least 16 years old.

3. Subscription & Billing

The Service is offered through paid subscription plans (Pro, Max, Enterprise). Plans are billed monthly. You may cancel at any time; access continues until the end of the billing period. Refunds are provided at our discretion. We reserve the right to modify pricing with 30 days' notice.

Promotional access codes (“Redemption Codes”) may be issued at our discretion for academic or evaluation purposes. Codes are non-transferable and subject to usage limits.

4. Usage Limits

Each plan includes a defined number of design generations per billing period. A “design” is defined as a new HDL code generation initiated through the platform. Iterative modifications within the same project/chat are not counted as separate designs. Exceeding your plan's limits may result in temporary suspension of generation capabilities until the next billing cycle.

5. Intellectual Property

Your Content: You retain all rights to designs, HDL code, testbenches, and GDSII outputs you create using the Service. We do not claim ownership of your content.
