3.1i ECS - DRC: "Consistency Check Error - I/O net xxxx has no pin on symbol"
Description
Keywords: Project Navigator, ECS, error
Urgency: Standard
General Description: ECS provides a DRC utility called "Consistency Check"; this utility verifies the connections such as symbol, net, netname, etc. One of the possible errors reported is:
"Symbol vs Schematic I/O net xxxx has no pin on symbol"
Solution
1
This error is caused when the symbol for the schematic has different ports. To correct this, regenerate the symbol to resolve port conflicts.
2
This error will also occur when a symbol of the top-level schematic is mistakenly created. To resolve this, delete the <top_level_name>.sym from the project's root directory.
