21.8.14 get_nets
(Ask a Question)Description
Returns a collection of nets matching the pattern you specify. You can only use this command as
source objects in create clock (create_clock) or create generated
clock (create_generated_clock) constraints and as
-through arguments in the set false path, set minimum delay,
set maximum delay, and set multicycle path constraints. Wildcards can be used to
select multiple nets at once. If no objects match the criteria, the empty string is
returned.
get_nets patternArguments
| Parameter | Type | Description |
|---|---|---|
pattern | string | Specifies the pattern to match the names of the nets to return. For example, get_nets N_255* returns all nets starting with the characters N_255, where * is a wildcard that represents any character string. This is mandatory. |
| Return Type | Description |
|---|---|
object | Returns an object representing the nets that match those specified in the pattern argument. |

Example
The following example sets maximum delay constraining all paths from RDATA1 port passing -through net_chkp1 net_chkqi nets.
set_max_delay 2 -from [get_ports RDATA1] -through [get_nets {net_chkp1 net_chkqi}]The following example specifies all paths through the nets Tblk/rm/n* to be false.
set_false_path –through [get_nets {Tblk/rm/n*}]The following example creates a clock on cknet net with a period of 2.5 ns.
create_clock -name mainCLK -period 2.5 [get_nets {cknet}]
