direction-determiner-T28

To determine digital IO signal direction for T28 semiconductor designs, apply priority rules using explicit user instructions, signal-direction dictionaries, and T28-specific naming heuristics. This validates direction values and ensures consistency with T28 device types and signal patterns.

Signal direction assignment in T28 IO ring design is the process of inferring whether a digital signal acts as input or output. It uses T28-specific naming heuristics for signals like SDI, SDO, and SCK to ensure correct signal flow and reduce manual configuration errors.

Yes, you can override automated signal direction heuristics with explicit instructions. The system adheres to a strict priority hierarchy: User Explicit instructions take precedence over Signal-Direction Dictionaries, which in turn override T28-specific naming heuristics.

The best way to validate direction values for T28 digital IO signals is to use an automated system that checks assigned inputs and outputs against T28 device types and signal patterns. This ensures consistency and prevents mismatches in IO ring configurations.

T28 naming heuristics might assign the wrong direction to a digital IO signal if conflicting definitions exist in a provided signal-direction dictionary, or if explicit user instructions override the heuristic. Check the priority rules to resolve the conflict.
