Lattice Semiconductor
In File List, the .lpc file is replaced with an .ipx file. The IPexpress manifest (.ipx) file is new with Diamond. The .ipx
file keeps track of the files needed for complex modules.
Using IPexpress with Lattice Diamond
Using IPexpress with Lattice Diamond is essentially same as with ispLEVER.
The configuration GUI tabs are all the same except for the Generation Options tab. Figure 8-48 shows the Genera-
tion Options tab window.
Figure 8-48. Generation Options Tab
Table 8-101. SERDES_PCS GUI Attributes – Generation Options Tab
Automatic
Force Module and Settings Generation
Force Settings Generation Only
Force Place & Route Process Reset
Force Place & Route Trace Process Reset
Note:
Automatic is set as the default option. If either Automatic or Force Settings Generation Only and no sub-options (Process Reset Options) are
checked and the HDL module is not generated, the reset pointer is set to Bitstream generation automatically.
After the Generation is finished, the reset marks in the process window will be reset accordingly.
GUI Text
Automatically generates the HDL and configuration(.txt) files as needed. Some
changes do not require regenerating both files.
Generates both the HDL and configuration files.
Generates only the attributes file. You get an error message if the HDL file also
needs to be generated.
Resets the Place & Route Design process, forcing it to be run again with the
newly generated PCS module.
Resets the Place & Route Trace process, forcing it to be run again with the newly
generated PCS module.
