MachXO sysIO Usage Guide
Appendix B. sysIO Attributes Using the ispLEVER Preference Editor or 
Diamond Spreadsheet View
You can assign the sysIO buffer attributes using the Pre-map Preference Editor GUI available in the ispLEVER or
the Spreadsheet View GUI in Diamond. The Pin Attribute sheet in ispLEVER and Port Assignments sheet in Dia-
mond list all the ports in your design and all the available sysIO attributes as preferences. When you click on each
of these cells you get a list of all the valid I/O preferences for that port. Each column takes precedence over the
next. Therefore, when you choose a particular IO_TYPE, the DRIVE, PULLMODE and SLEWRATE columns will
only list the valid combinations for that IO_TYPE. The user can lock the pin locations using the pin location column
of the Pin Attribute sheet. Right-click on a cell to list all the available pin locations. The Preference Editor and the
Spreadsheet View will also do a DRC check to search for any incorrect pin assignments.
You can enter the DIN/ DOUT preferences using the Cell Attributes sheet of the Preference Editor. All the prefer-
ences assigned using the Preference Editor and the Spreadsheet View are written into the preference file (.prf).
Figure 8-5 shows the Pin Attribute sheet and the Cell Attribute sheet view of the Preference Editor. For further infor-
mation on how to use the Preference Editor, please refer to the ispLEVER Help documentation. You can get to this
in the Help menu option of the software.
