Valid Configurations For Using the EDA Simulator Link Software with MATLAB Applications

The following list provides samples of valid configurations for using the ModelSim HDL simulator and the EDA Simulator Link software with MATLAB software. The scenarios apply whether the HDL simulator is running on the same or different computing system as the MATLAB software. In a network configuration, you use an Internet address in addition to a TCP/IP socket port to identify the servers in an application environment.

• An HDL simulator session linked to a MATLAB function foo through a single instance of the MATLAB server

• An HDL simulator session linked to multiple MATLAB functions (for example, foo and bar) through a single instance of the MATLAB server

• An HDL simulator session linked to a MATLAB function foo through multiple instances of the MATLAB server (each running within the scope of a unique MATLAB session)

• Multiple HDL simulator sessions each linked to a MATLAB function foo through multiple instances of the MATLAB server (each running within the scope of a unique MATLAB session)

• Multiple HDL simulator sessions each linked to a different MATLAB function (for example, foo and bar) through the same instance of the MATLAB server

• Multiple HDL simulator sessions each linked to MATLAB function foo through a single instance of the MATLAB server

  Although multiple HDL simulator sessions can link to the same MATLAB function in the same instance of the MATLAB server, as this configuration scenario suggests, such links are not recommended. If the MATLAB function maintains state (for example, maintains global or persistent variables), you may experience unexpected results because the MATLAB function does not distinguish between callers when handling input and output data. If you must apply this configuration scenario, consider deriving unique instances of the MATLAB function to handle requests for each HDL entity.

Notes   Shared memory communication is an option for configurations that require only one communication link on a single computing system. TCP/IP socket communication is required for configurations that use multiple communication links on one or more computing systems. Unique TCP/IP socket ports distinguish the communication links. In any configuration, an instance of MATLAB can run only one instance of the EDA Simulator Link MATLAB server (hdldaemon) at a time. In a TCP/IP configuration, the MATLAB server can handle multiple client connections to one or more HDL simulator sessions.

Valid Configurations For Using the EDA Simulator Link Software with Simulink Software

The following list provides samples of valid configurations for using the ModelSim HDL simulator and the EDA Simulator Link software with Simulink software. The scenarios apply whether the HDL simulator is running on the same or different computing system as the MATLAB or Simulink products. In a network configuration, you use an Internet address in addition to a TCP/IP socket port to identify the servers in an application environment.

• An HDL Cosimulation block in a Simulink model linked to a single HDL simulator session

• Multiple HDL Cosimulation blocks in a Simulink model linked to the same HDL simulator session

• An HDL Cosimulation block in a Simulink model linked to multiple HDL simulator sessions

• Multiple HDL Cosimulation blocks in a Simulink model linked to different HDL simulator sessions

Notes   HDL Cosimulation blocks in a Simulink model can connect to the same or different HDL simulator sessions. TCP/IP socket communication is required for configurations that use multiple communication links on one or more computing systems. Unique TCP/IP socket ports distinguish the communication links. Shared memory communication is an option for configurations that require only one communication link on a single computing system.
