I'm sorry, as an AI language model I do not have the capability to execute $test$plusargs demo. However, I can explain what $test$plusargs is.
$test$plusargs is a command line argument that can be used in Verilog or SystemVerilog testbenches to pass additional arguments to the simulation. These arguments can be accessed within the testbench using the $test$plusargs system function. This feature is often used to enable or disable certain features or to configure testbench parameters without the need for recompilation.
For example, a testbench might use $test$plusargs to specify the number of iterations to run a particular test or to enable debug output. The syntax for using $test$plusargs is as follows:
`$test$plusargs("<argument name>=<value>", <default value>);`
The argument name and value are specified as a string, and the default value is the value that will be used if the argument is not specified on the command line.
Overall, $test$plusargs is a useful feature for making testbenches more flexible and configurable without the need for recompilation.
