Setting Individual Logic Options that Affect Fitting
Quartus II logic options allow you to set attributes without editing the
source code. You can specify Quartus II logic options for individual nodes
and entities in the Assignment Editor and can specify global default logic
options in the More Fitter Settings dialog box, which is available by clicking
More Settings in the Fitter Settings page of the Settings dialog box. For
example, you can use logic options to specify that the signal should be
available throughout the device on a global routing path, specify that the
Fitter should create parallel expander chains automatically, specify that the
Fitter should automatically combine a register with a combinational
function in the same logic cell, also known as “register packing,” or limit the
length of carry chains, cascade chains, and parallel expander chains.
