Catalyst Enterprises, Inc. TA700/TA800 as Target
100
Enter a Base Target Address and set up target data with Data or a pre-defined Data
Block. Note, however, that this data will not be stored.
Figure 93 Setting Exerciser as Target
Note: When set up this way the TA700/TA800 will only respond with specifically
programmed responses and not as a random target.
Enable Local Memory
Check the Enable Local Memory check box on the Exerciser Program tab. Note,
however that this enables the TA700/800 to behave as a real target, but does not offer
the flexibility to modify target response behaviour for specialized testing.
The PCI exerciser allows the TA700/800 to be programmed to act as a 1 MB random
access memory behaving like a real target while still operating as an Analyzer. The
local memory becomes active when the Enable Local Memory box is checked on the
Exerciser program page and the Run button is pushed. The local memory will stop
responding after the exerciser is manually stopped.
Setting the Base Address The TA700/800 base address is assigned by the system BIOS at boot up
time. The first 20 bits (5 bytes) are assigned to the local memory and
initially set to don’t care. The user may change these bits to use the local
memory for some specific memory access. You may assign any target
address if the TA700/TA800 is being used in a passive environment.
Note: If you wish for local memory to correspond to a range of addresses you need to
specify that range with X’s. e.g. 0xA0000XXX which corresponds to 4K address
range starting from 0xA0000000.
