portRegTest
Bit write/read test of the ASIC SRAMs and registers.
Syntax portRegTest [-ports list][-skiptests mask]
Availability Admin
Description Use this command to verify that SRAM and register data bits in each
ASIC can be independently written and read.
To verify the data bits, write a walking 1 pattern to each location —
write a pattern of 0x00000001 to register N, read, and compare to be
sure that the pattern is the same. Shift the pattern one bit to the left (to
0x00000002), repeat the write, read, and compare cycle. Shift again
and repeat until the last writable bit in register N is reached
(0x80000000 for a 32-bit register).
For example, use the following pattern to test a 6-bit register:
1. 0x0001
2. 0x0002
3. 0x0004
4. 0x0008
5. 0x0010
6. 0x0020
7. 0x0040
8. 0x0080
9. 0x0100
10.0x0200
11.0x0400
12.0x0800
13.0x1000
14.0x2000
15.0x4000
16.0x8000
Repeat the above steps until all ASIC SRAMs and registers have been
tested.
