Predefined Attribute Fields
The following table describes the fixed list of attribute fields provided in
each LogicWorks design. Attribute fields cannot be added or deleted in
LogicWorks.
Field Name Used In Description
CctName Design
Design file name. Sets the window title and name of
next saved file.
Delay.Dev Device Specifies device delay. For most devices, a single
decimal integer 0 to 32,767. For Clock and One Shot
devices, two integers separated by commas. Should
be set using the Parameters command, and not edited
manually.
Delay.Pin Pin A decimal integer specifying pin delay in the range 0
to 32,767. Should be set using the Simulation Params
command and not edited manually.
Initial.Pin Pin This field is used to specify the initial state for
storage devices when a Reset or Clear Simulation
operation is performed. It can contain a single
character, either 0, 1, X, or Z.
Initial.Sig Sig This field is used to specify the initial state for a
signal. It can contain a single character, either 0, 1,
X, or Z.
Invert.Pin Pin This field is used to specify logical inversion on
device pins. Any non–empty value indicates
inversion should be done.
Name Device,
signal
The device or signal name. This is the field set using
the text tool on the schematic or the Name command
in the pop–up menu.
Spice Device,
Design
Holds simulation parameters for SPICE–based
simulators. Not used internally.
Value Device Component value to appear on the schematic. Not
used internally.
