User Guide
dma_rd_test Procedure
Use the dma_rd_test procedure for DMA reads from the Endpoint memory to the
BFM shared memory.
dma_wr_test Procedure
Use the dma_wr_test procedure for DMA writes from the BFM shared memory to the
Endpoint memory.
dma_set_rd_desc_data Procedure
Use the dma_set_rd_desc_data procedure to configure the BFM shared memory for
the DMA read.
dma_set_wr_desc_data Procedure
Use the dma_set_wr_desc_data procedure to configure the BFM shared memory for
the DMA write.
Table 17–56. dma_rd_test Procedure
Location altpcietb_bfm_driver_rp.v
Syntax dma_rd_test (bar_table, bar_num, use_msi, use_eplast)
Arguments
bar_table Address of the Endpoint bar_table structure in BFM shared memory.
bar_num BAR number to analyze.
Use_msi When set, the Root Port uses native PCI express MSI to detect the DMA completion.
Use_eplast When set, the Root Port uses BFM shared memory polling to detect the DMA completion.

Location altpcietb_bfm_driver_rp.v
Syntax dma_wr_test (bar_table, bar_num, use_msi, use_eplast)
Arguments
bar_table Address of the Endpoint bar_table structure in BFM shared memory.
bar_num BAR number to analyze.
Use_msi When set, the Root Port uses native PCI Express MSI to detect the DMA completion.
Use_eplast When set, the Root Port uses BFM shared memory polling to detect the DMA completion.
Table 17–58. dma_set_rd_desc_data Procedure
Location altpcietb_bfm_driver_rp.v
Syntax dma_set_rd_desc_data (bar_table, bar_num)
Arguments
bar_table Address of the Endpoint bar_table structure in BFM shared memory.
bar_num BAR number to analyze.
Table 17–59. dma_set_wr_desc_data_header Procedure
Location altpcietb_bfm_driver_rp.v
