Synopsis

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

Description

A locbus_agent_ddma component is connected to the demand-mode DMA pins of the FPGA (unit under test), and outputs a signal of type locbus_ddma_in_t. The stimulus process then uses this signal in calls to the procedures provided by the PLXSIM package in order to perform demand-mode DMA local bus transfers. The arrangement is shown here in simplified form:

The following procedures input a signal of type locbus_ddma_in_t:

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