3.13.1. Supported Port Size register

The Supported_Port_Sizes register characteristics are:

Purpose

Each bit location is a single port size that is supported on the device, that is, 32-1 in bit locations [31:0]. When the bit is set then that port size is permitted. By default the RTL is designed to support all port sizes, set to 0xFFFFFFFF.

The value returned by this register is controlled by the input tie-off tpmaxdatasize. The external tie-off, tpmaxdatasize, must be set during finalization of the ASIC to reflect the actual number of tracedata signals being wired to physical pins. This is to ensure that tools do not attempt to select a port width that cannot be captured by an attached TPA.

The value on tpmaxdatasize causes bits within the Supported Port Size register that represent wider widths to be clear, that is, unsupported.

Usage constraints

There are no usage constraints.

Configurations

This register is available in all configurations.
