Software sysIO Attributes
sysIO attributes can be specified in the HDL, using the Preference Editor GUI in ispLEVER
in Lattice Diamond™ design software, or in the ASCII Preference file (.perf) directly. Appendices A, B and C list
examples of how these can be assigned using each of the methods mentioned above. This section describes in
detail each of these attributes.
IO_TYPE
This is used to set the sysIO standard for an I/O. The V
the attribute names itself. There is no separate attribute to set the V
able I/O types.
