Synopsis

locbus_ddma_out_t is an opaque record type used to bundle together the signals required for demand-mode DMA local bus transfers.

Description

The stimulus process uses the functions provided by the PLXSIM package to drive a signal of type locbus_ddma_out_t. This signal is then input by a locbus_agent_ddma component, which is in turn connected to the demand-mode DMA pins of the FPGA (unit under test). The arrangement is shown here in simplified form:

The following procedures output a signal of type locbus_ddma_out_t:

Since it is an opaque datatype, the members of locbus_ddma_out_t should not be accessed, as they are subject to change in future versions of the PLXSIM package.
