Apparatus and mechanism to support multiple time domains in a single SoC for time sensitive network

A method comprising:

• receiving a first request from an endpoint;
• based on the first request:
• communicatively coupling the endpoint to a first communication time domain source of a set of communication time domain sources;
• and
• concurrently, communicatively coupling the endpoint to an application time domain source of a set of application time domain sources;
• determining a failure associated with the first communication time domain source;
• receiving a second request that specifies to communicatively couple the endpoint to a second communication time domain source;
• and
• based on the failure and the second request, communicatively coupling the endpoint to the second communication time domain source.

A circuit device comprising:

• a register configured to store a value based on a request from an endpoint;
• a set of communication domain inputs configured to couple to a set of communication time domain sources;
• a first application domain input configured to couple to a first application time domain source;
• an output configured to couple to the endpoint;
• a crossbar coupled to the register, the set of communication domain inputs, the first application domain input, and the output;
• a second application domain input coupled to the crossbar and configured to couple to a second application time domain source;
• and
• programable logic coupled to the register and the crossbar and configured to cause the crossbar to, based on the value, couple the endpoint to a first communication time domain source of the set of communication time domain sources and couple the endpoint to the first application time domain source and the second application time domain source concurrently.

A device comprising:

• a register configured to store a bit mask based on a request from an endpoint;
• a set of inputs that includes a first input configured to couple to a communication time domain source and a second input configured to couple to an application time domain source;
• a set of outputs that includes a first output configured to couple to the endpoint;
• and
• a set of programmable logic gates coupled to the set of inputs and the set of outputs and configured to:
• provide a first communication path between the first input and a first subset of the set of outputs that includes the first output to couple the communication time domain source to the endpoint based on the bit mask;
• and
• provide a second communication path between the second input and a second subset of the set of outputs based on the bit mask.
