Setting up cores synchronization

Figure 16. Synchronization between cores

The SYnch command is used for Start/Stop synchronization in a multi-processor or multi-

core environment.

SYnch.CONNECT - Establishes a connection to another emulator by using the InterCom

system. Multiple names can be used to connect to multiple systems.

SYnch.MasterGo – Starting this emulator all other emulators start, the SlaveGo function is

activated.

SYnch.MasterBreak – Breaking this emulator system simultaneously stop all emulators

which have the SlaveBreak option activated.

SYnch.MasterStep – Stepping this emulator step all other emulators which have the

SlaveStep function activated.

SYnch.SlaveGo – The emulator starts, when the master emulator starts.

SYnch.SlaveBreak – The emulator stops, when the master emulator stops.

SYnch.SlaveStep – The emulator steps, when the master emulator steps.

To test the INTERCOM system the INTERCOM.PING command can be used. If the

connection is not working (step/break/go in one window are not made same in second core

window even if synch options are all allowed) you can use the ping command. If it returns

around 100µs this means you have connected core to itself. Check the Synch.CONNECT

settings.

Writing Synch command in TRACE32 PowerView command line brings up windows for

synchronization options.
