Memtest sample application
Supports models:
The Memtest sample application uses the ZBT sample FPGA design (Verilog, VHDL) to test the SSRAM on an ADM-XRC series card.
Depending on whether or not the -usedma or +usedma command-line options are given, it uses either programmed I/O or DMA to transfer data to and from the SSRAM. In general, DMA is efficient for bulk data transfers while programmed I/O is efficient for random access to registers within the FPGA.
Syntax:
memtest [options ...]
Options:
Option | Type | Meaning |
-banks | hexadecimal integer | Bitmask of banks to test (default 0xFFFFFFFF) |
-card | base 10 integer | ID of card to open |
-index | base 10 integer | Index of card to open |
-lclk | real number | Local bus clock frequency to use, in MHz (default 33.0) |
-repeat | base 10 integer | Number of times to perform tests (default 1) |
-speed | Do not test SSRAM access speed | |
+speed | Test SSRAM access speed (default) | |
-usedma | Use programmed I/O for tests | |
+usedma | Use DMA for tests (default) |
