Detailed Description

Class that implements the Simics transaction interface and translates it into a TLM transaction.

The TLM2 return codes are translated to Simics like this: TLM_OK_RESPONSE => Sim_PE_No_Exception, TLM_ADDRESS_ERROR_RESPONSE => Sim_PE_IO_Not_Taken or Sim_PE_Inquiry_Outside_Memory on inquiry access, remaining TLM2 errors => Sim_PE_IO_Error or Sim_PE_Inquiry_Unhandled on inquiry access

Member Function Documentation

◆ issue()

exception_type_t simics::systemc::simics2tlm::Transaction::issue ( transaction_t *  transaction,
uint64  addr 
)
overridevirtual

Implements simics::systemc::iface::TransactionInterface.

◆ set_deferrable()

void simics::systemc::simics2tlm::Transaction::set_deferrable ( bool  enable)
inline

Toggle code paths for deferred transactions.

When enabled (true), the code path that checks whether the
incoming Simics transaction_t can be deferred will be used. The
actual decision still depends on the Simics runtime function
SIM_transaction_is_deferrable(transaction); both checks must pass
for a transaction to be deferred. This is a slower path.
When disabled (false, the default), the synchronous path is used. This is a faster path as there is no need to create callbacks to handle deferred transactions.
