DFF1
and DFF0
are MAX PLUS II primitives used to define the power up state of registers in MAX® 7000AE devices.
Versions of Synopsys Smart Models created prior to October 1998 do not support the Altera® DFF1
and DFF0
primitives. Synopsys
Smart Models version 10002 and higher do support these primitives.
The Smart Model file used for MAX PLUS II output files are named altera<version number>.ccl, where the version number is 10002 or higher.
You can use Synopsys Smart Models in many third-party simulation tools (e.g., Synopsys VSS and Workview Office VCS). To obtain Synopsys Smart Models, contact Synopsys Logic Modeling.
