Merging TLA700 Modules
This chapter describes how to merge TLA700 series logic analyzer and pattern
generator modules to form wider modules, that all operate from a single time
base.
A merged logic analyzer module set consists of a master logic analyzer module
and up to four slave logic analyzer modules that are physically connected
together by a merge cable and are merged in software. Review the guidelines
under
Logic Analyzer Module Merging Rules
and then follow the steps to
physically connect the modules together before installing the modules in the
mainframe.
A merged pattern generator module set consists of a master pattern generator
module and up to four slave pattern generator modules merged in software.
Review the guidelines under
TLA7PG2 Pattern Generator Module Merging
Rules
on page 26 before installing the modules in the mainframe.
Logic Analyzer Merging Rules
The following logic analyzer module merging rules must be followed:
H
Only modules with 102 or 136 channels can be merged.
H
Logic analyzer modules must be in adjacent slots and physically connected.
H
Logic analyzer modules cannot be merged across mainframes.
H
Merging logic analyzer modules with unequal memory depths will result in
the merged modules assuming the depth of the shallowest module.
H
Merging logic analyzer modules with unequal speeds will result in the
merged modules assuming the speed of the slowest module.
H
When merging logic analyzer modules of unequal channel widths, use the
logic analyzer module with the highest number of channels as the master
module. If there is a second slave module, the first slave must have greater
than or equal the number of channels as the second slave module. Slave 3
cannot have more channels than the master, slave 1 or slave 2. Slave 4
cannot have more channels than the master, slave 1, slave 2, or slave 3. See
Figure 17 on page 27 to determine the location of the master module with
the merged module set.
H
The logic analyzer modules must have the same firmware version.
