Hi Kyungmin Kyungmin,

I have to following hints at resolving the errors

1. Let us concentrate on error 2 first since that is simple, the error is saying that you have to set the solver type to Fixed type, I think the current setting is variable type solver and also do the suggested things the error message is displaying in diagnostics
2. the signals that are entering the system should not be continuous but should have a sample time say 0.01 or 0.001 something like that, before the Digital section you can have a data conversion block that converts to single and feeds that single data type to your Digital section

the above are some of the hints that may solve your issue

Thank you
