Vivado - "[Common 17-14] Message '' appears 100 times and further instances of the messages will be disabled..."

Description

After elaborating, synthesizing, or implementing my design in the Vivado tool, an information message similar to the following appears stating that a particular message is found more than 100 times and future messages will be disabled:

INFO [Common 17-14] Message Synth 8-113' appears 100 times and further instances of the messages will be disabled. Use the Tcl command set_msg_config to change the current settings.

What does this warning mean and how can I increase the message limit?

Solution

In Vivado there is a limit for the number of warnings and errors which are displayed by the tool for a particular error or warning; the default value of this limit is 100. 

For example, if you have a 'Synth 8-113' warning on a large number of signals in your design, the tool shows only the first 100 instances of this warning.


You can check the limit value for any message by using the get_msg_config command (e.g. "get_msg_config -limit -id "Synth 8-11")

In Vivado 2012.4 and earlier use the get_msg_limit command (e.g., "get_msg_limit -id "Synth 8-11"").


To increase the message limit for this message ID, use the set_msg_config Tcl command (e.g., "set_msg_config -id "Synth 8-11" -limit 500"); this will increase the message limit for this warning from 100 to 500.

In Vivado 2012.4 and earlier, use the set_msg_limit TCL command (e.g., "set_msg_limit -id "Synth 8-11" 500").


In general, if you want to know the default value of the message limit for all the message IDs, you can use the TCL command "get_param messaging.defaultLimit ".


To increase the default message limit for all the message IDs, use the TCL command "set_param messaging.defaultLimit 300 "; this will increase the message limit for all the messages (warnings and errors) from the default value of 100 to 300.

Using the set_param messaging.defaultLimit 500 command overrides the value given for a specified message ID that is using the set_msg_limit TCL command.

For more information on these Tcl commands, see the Vivado Tcl User Guide (UG835).

Note: In Vivado 2013.1 the message limit was raised from 50 to 100 messages.
