Pick

Purpose

The pick command allows you to select an object in the main EPIC window by location.

Syntax

pick [-a] [-n] [-q] [-e] [-m] [-s] [-p] [x_loc y_loc] [layer_name]

where:

-a picks in all layers, whether they are visible or invisible (default is to pick only visible objects).

-n picks a component if the pick location is over a component pin or picks a site if the pick location is over a site. Forces EPIC to pick the site or component rather than the pin.

-q lists the name and other information of the object the cursor is currently over into the EPIC history area. It does this without selecting the object.

-e generates an editblock command (that is, starts the logic block editor) if a component is found at the specified x, y coordinates.

-m selects a macro if a macro component is found at the specified x, y coordinates. Otherwise selects a regular pick.

-s selects a net if a route segment is found at the specified x, y coordinates.

-p selects a pin if the pick location is over a pin.

x_loc and y_loc represent absolute screen coordinates. For applicable commands, these coordinates will appear in the design name.epl file. All x-y values must be between 32000. If coordinates are not specified, the default is to use the current mouse cursor position.

layer name is the specific layer to pick in. If layer name is not specified, all layers are picked. Layer name can be components, hilite, links, local lines, long lines, pinwires, ratsnests, routes, select, sites, text.

Example

The following command will select the object the cursor is currently over:

pick

The following command will select the object at coordinates 12400 234:

pick 12400 234

The following command will select the site the cursor is currently over:

pick sites

The following command is the same as above except that it will select a site even if the site layer is not visible.

pick -a sites

Notes

The pick command is most useful when it is assigned to a hot key or a mouse button.

Syntax

playback [-d] [-r] [-i] [-p] [-s] file_name

• -d will not draw the edit area while playing back the script file.
  
  
• -r ignores these commands during playback: editblock, getattr, help, null, pan, pause, post, and zoom. This option is used when you recover from an aborted EPIC session.
  
  
• -i does an unbutton all and an unalias all before playing back the script file
  
  
• -p does not post forms during playback.
  
  
• -s displays each command in the history area as it is performed.
  
  
• file_name is the name of the .scr file to read EPIC commands from.

post cmd | drc | find | list | new | open | macnew | macopen | addmacro | playback | | view | autorouteall | autoplaceall | trace | tracesum

post traceerr pcf_index

post [-n] exit | cmd

• -m posts the Save As Macro dialog box
  
  
• -n exit posts the Exit dialog box (If you have not made any changes to the design, EPIC will terminate without posting the dialog box.)
  
  
• -n cmd posts the command dialog box without buttons (OK, Apply, Cancel). Once the command is entered and RETURN is pressed, the command is executed and the command line dialog box automatically unposts itself.
  
  
• pcf_index is the position of the constraint within the constraint file and the EPIC List dialog box. For example, the first constraint listed is number 0, and so forth.
  
  

The allowable dialog box type entries are explained in the following table.
