Signal Name Conventions
Signal names may contain either a port designation or a serial designation, or a
combination of the two designations. Signal naming conventions are as follows:
Port Number Only. Individual signals that apply to a particular port are designated by
the Signal Mnemonic, immediately followed by the Port Designation. For example,
Transmit Enable signals would be identified as TxEN0, TxEN1, and TxEN2.
Serial Number Only. A set of signals which are not tied to any specific port are
designated by the Signal Mnemonic, followed by an underscore and a serial
designation. For example, a set of three Global Configuration signals would be
identified as CFG_1, CFG_2, and CFG_3.
Port and Serial Number. In cases where each port is assigned a set of multiple
signals, each signal is designated in the following order: Signal Mnemonic, Port
Designation, an underscore, and the serial designation. For example, a set of three
Port Configuration signals would be identified as RxData0_0 and RxData0_1,
RxData1_0 and RxData1_1, and RxData2_0 and RxData2_1.
