Lattice ispTRACY Usage Guide
ispTRACY Core Linker
Once the ispTRACY core is created, it must be linked into the target design. This is accomplished through the Core
Linker program. The Core Linker program allows the user access to internal and external signals of the target
design. The internal signals can be named signals or component ports. This window also displays the available isp-
TRACY ports. To connect ispTRACY signals, the desired signal(s) are selected in the left-hand signal window. Sig-
nals chosen from this window are reflected in the Selected signals window. Signals must be highlighted in this
window, the ispTRACY port window and then click on the connect button to connect the signals in the RTL code.
Multiple instances (for example, a data bus) can be connected at once by highlighting the first signal, holding down
the SHIFT key and clicking on the last desired signal. Figure 14-4 shows the ispTRACY Core Linker window.

When you click the Save button (or File -> Save menu selection), the Core Linker will create modified versions of
your source file, with the ispTRACY core linked into these modified files. Only design files that are directly con-
nected to the core will be modified. A dialogue box will indicate which files have been changed and will need to be
replaced in the design project for ispTRACY to function. The design files names will be the original files names with
the module name for the ispTRACY core (from the IPexpress ispTRACY core generation) appended. Figure 14-5
shows the changed files dialogue box.
