Regular expressions

Regular expressions, wildcard characters, and hierarchy delimiters “/” are recognized in the following format.

'[ Instance_Name / ] Terminal_Name  [ : Pin_Name ] [ : PinFig_Name ]" | "[ Instance_Name /  ] " .* "

'("A:A" "left" 0.01 "locked")

'("A/.*" "left" 0.01 "locked")

The following expression will not be recognized:

'("X<.*" "right" 0.1 "floating" )

'("X<[0-1]>" "right" 0.1  "floating" )

'("X<[0-1]>:X<[0-2]""right" 0.1  "floating" )

Numeric Pins

Numeric pin names are recognized.

'("3.1:4.1" "right" 0.1  "floating" )

Terminal names and pin names

Terminal and pin names are named OA objects. Therefore, you can assign constraints to:

• Terminal names

Constraints assigned to terminal names are applicable to all the pins and pinFig objects in the terminal.

• Terminal names and pin names

Constraints are applicable only to the specified pin in the specified terminal in the following format.

'("Terminal_Name:Pin_Name" "Pin_Edge" Pin_Pitch "Pin_Status")

'("A" "Top" 0.01 "locked")

'("A:A1" "Top" 0.01 "locked")

'("A:A2" "Top" 0.01 "locked")

Individual PinFigs

Here, pin figures that are placed together to implement a feed through connection. You can enter constraints for each pin shape in the following format.

'("Terminal_Name:Pin_Name:PinFig_Name" "Pin_Edge"   Pin_Pitch "Pin_Status")

'("I1/A:A:A1" "left" 0.01 "locked")

Pin names for level-1 pins

When you specify instance pins, they correspond to the instance master’s Terminal_Name:Pin_Name:PinFig_Name. Ensure that you specify the instance name while defining constraints for level-1 or soft block instance pins in the following format.

'("Instance_Name/Terminal_Name:Pin_Name:PinFig_Name" "Pin_Edge"   Pin_Pitch "Pin_Status")

'("I1/A:A:A1" "left" 0.01 "locked")

Wildcard characters and hierarchy delimiters

To specify the constraints on all terminals and pins for a given instance, enter only the instance name and a ".*" after the hierarchy delimiter "/".

To specify the constraints on the top-level pins, enter ".*".

You can use ".*" as a wildcard in regular expressions for names.

You can also specify regular expressions in pin or pinFig names.

Using hierarchy delimiter:

'("I1/.*" "left" 0.01 "locked")

Using wildcard:

'(".*" "left" 0.01 "locked")

'("ADDRESS_.*" "left" 0.01        "locked")

'(".*:PIN246.*" "left" 0.01        "locked")

'(".*:PIN246.*:PinFIG1.*" "left" 0.01 "locked")

'("D[1-3]:P.*" "right" 0.1 "floating" )

Vector single and vector bit notations

You can include vector single and vector bit notations, such as A<0:4>:A<0:4>, in pin names. Such vector notations are automatically expanded to their corresponding vector bits.

'("A<0:4>:A<0:4>" "Top" 0.01 "locked")
