How Sim-Credits work
- After monthly sim quota is used: 1 successful simulation = 1 Sim-Credit from your balance
- After monthly Standard AI quota: 1 Standard AI interpretation = 1 Sim-Credit
- After monthly Advanced AI quota: 1 Advanced AI interpretation = 3 Sim-Credits
Large CIDER, device, or long transient SPICE runs often need Pro+ (up to 15 min) or Ultra (up to 30 min) run limits.
All plans include tenant-isolated workspaces and secure access. Failed or cancelled runs do not consume credits.
