|
*
|
|
* This file contains utility functions to test memory.
|
|
*
|
|
* <b>Memory test description</b>
|
|
*
|
|
* A subset of the memory tests can be selected or all of the tests can be run
|
|
* in order. If there is an error detected by a subtest, the test stops and the
|
|
* failure code is returned. Further tests are not run even if all of the tests
|
|
* are selected.
|
|
*
|
|
* Subtest descriptions:
|
|
* <pre>
|
|
* XIL_TESTMEM_ALLMEMTESTS:
|
|
* Runs all of the following tests
|
|
*
|
|
* XIL_TESTMEM_INCREMENT:
|
|
* Incrementing Value Test.
|
|
* This test starts at 'XIL_TESTMEM_INIT_VALUE' and uses the
|
|
* incrementing value as the test value for memory.
|
|
*
|
|
* XIL_TESTMEM_WALKONES:
|
|
* Walking Ones Test.
|
|
* This test uses a walking '1' as the test value for memory.
|
|
* location 1 = 0x00000001
|
|
* location 2 = 0x00000002
|
|
* ...
|
|
*
|
|
* XIL_TESTMEM_WALKZEROS:
|
|
* Walking Zero's Test.
|
|
* This test uses the inverse value of the walking ones test
|
|
* as the test value for memory.
|
|
* location 1 = 0xFFFFFFFE
|
|
* location 2 = 0xFFFFFFFD
|
|
* ...
|
|
*
|
|
* XIL_TESTMEM_INVERSEADDR:
|
|
* Inverse Address Test.
|
|
* This test uses the inverse of the address of the location under test
|
|
* as the test value for memory.
|
|
*
|
|
* XIL_TESTMEM_FIXEDPATTERN:
|
|
* Fixed Pattern Test.
|
|
* This test uses the provided patters as the test value for memory.
|
|
* If zero is provided as the pattern the test uses '0xDEADBEEF".
|
|
* </pre>
|
|
*
|
|
* <i>WARNING</i>
|
|
*
|
|
* The tests are <b>DESTRUCTIVE</b>. Run before any initialized memory spaces
|
|
* have been set up.
|
|
*
|
|
* The address provided to the memory tests is not checked for
|
|
* validity except for the NULL case. It is possible to provide a code-space
|
|
* pointer for this test to start with and ultimately destroy executable code
|
|
* causing random failures.
|
|
*
|
|
* @note
|
|
*
|
|
* Used for spaces where the address range of the region is smaller than
|
|
* the data width. If the memory range is greater than 2 ** width,
|
|
* the patterns used in XIL_TESTMEM_WALKONES and XIL_TESTMEM_WALKZEROS will
|
|
* repeat on a boundry of a power of two making it more difficult to detect
|
|
* addressing errors. The XIL_TESTMEM_INCREMENT and XIL_TESTMEM_INVERSEADDR
|
|
* tests suffer the same problem. Ideally, if large blocks of memory are to be
|
|
* tested, break them up into smaller regions of memory to allow the test
|
|
* patterns used not to repeat over the region tested.
|
|
*
