2.1.21 ASB Channel Mapping

In the Analog System Builder, you must specify a name for each peripheral that you configure. For example, you can name a Voltage Monitor MYVOLT, and this name appears in the generated netlists as MYVOLT.

Internally, the analog block (AB) assigns fixed names to analog ports, such as AV0, AV1,..., AC0, AC1,..., AT0, AT1, and so on. Each of these ports is physically connected to a specific package pin. For example, AV0 corresponds to physical pin 99 on the package, and AV1 corresponds to physical pin 103.

Physical pin placement information is conveyed through the netlist. When Designer imports a netlist containing an analog block, it infers the pin placement directly from the netlist data.

As a result, the Analog System Builder maps each user‑defined logical channel to a corresponding physical channel on the analog block. If you change the die or package for a project, the Analog System Builder automatically resets all user‑assigned pins to UNASSIGNED.
