A trace is a special marker placed on a worksheet that identifies a node to be traced in the digital simulation of the design. To keep the design from being cluttered, the trace name is not visible on the schematic. To view the contents of a trace, use the INQUIRE command.
To place a trace, select Trace Name. Draft displays the prompt: "Trace Name?" Enter the name you wish this sig-nal to be displayed as in the simulator. Draft displays:
Iplace Value Find Jump Zoom
Select Place to place the trace on the worksheet. After placing the trace, the ''Trace Name?" prompt returns. You can place another trace or press <Esc> to return to the main menu level.
NOTE: If you always stay on grid, the trace is always correctly positioned to connect to a wire or bus. Just move the pointer on the wire to place the trace.
Select Value to edit value for the trace before you place the trace. When you select Value, the prompt ''Trace Name?"
displays followed by the current value. Edit the value using the editing techniques describe previously When you finish editing the trace name, press <Enter>.
A trace may be placed on either a net or a bus. The trace name may consist of any printable characters including spaces, except a period. If the display name contains a left or right square bracket, then the name is considered to be a bus name and the trace must be placed on a bus. For buses, the format of the bus may be specified after the right square bracket in the name. The format is a single character from the following list:
B Binary format H Hexadecimal format
ADD 5
DATA [0 •• 15) D
D Decimal format

A vector is a special marker placed on the worksheet that identifies a node to be stimulated by a test vector. The test vectors are referred to by column number, therefore, the vector placed on the worksheet has a vector column value.
To keep the design from being cluttered, the vector column is not visible on the schematic. To view the vector column number of a particular vector, use the INQUIRE command.
To place a vector, select Vedor. Draft displays the prompt:
''Vector Column?" Enter the column number of the vector.
Draft displays:
Iplace Value Find Jump Zoom
Select Place to place the vector on the worksheet.
When the vector is placed, the "Vector Column?" prompt returns. You can place another vector or press <Esc> to return to the main menu level.
~ NOTE: If you always stay on grid, the vector is always correctly positioned to connect to a wire or bus. Just move the pointer on the wire to place the vector.
Value Select Value to edit the vector column. When you select Value, the prompt ''Vector Column?" displays followed by the current value. Edit the value by positioning the cursor with the <~> and <~> keys, and the <Home> and <End>
keys, erasing characters with <Backspace> and <Delete>, and adding new characters with the alphanumeric keys.
When you finish editing the vector column, press <Enter>.
Vector column format The vector column indicates which column of the test vector file to use when the simulation is run. The column number is a decimal whole number such as 5.

A stimulus is a special marker placed on a worksheet that identifies a node to be stimulated by in the digital
simulation of the design. The stimulus is an expression describing the pattern of logic states. To keep the design from being cluttered, the stimulus pattern is not visible on the schematic. To view the contents of the stimulus, use the INQUIRE command.
To place a stimulus, select Stimulus. Draft displays the prompt: "Stimulus?" Enter the value of the stimulus. Draft displays:
Iplace Value Find Jump Zoom
Select Place to place the stimulus on the worksheet.
When the stimulus is placed, the ustimulus?" prompt returns. You can place another stimulus or press <Esc> to return to the main menu level.

orbus. Just move the pointer on the wire to place the stimulus.
Value
Select Value to edit the value of the stimulus. When you select Value, the prompt "Stimulus?" displays followed by the current value. Edit the value by positioning the cursor with the <~> and <--+> keys, and the <Home> and <End>keys, erasing characters with <Backspace> and <Delete>, and adding new characters with the alphanumeric keys.
When you finish editing the value, press <Enter>.
Stimulus value format
The stimulus describes the pattern of logic states to be applied to a net in the simulation. The pattern is described using a series of functions. A value must have a minimum of one function. The maximum is limited to the number of functions that can be placed in the text associated with the stimulus object.There are two types of functions: set and branch. At least one space is required between each function.
