I've just started using Electric for class, and I'm having trouble

hook anything into the CLR port. The simulation fails to run with this error...

If I try to use a T FF, it fails to find the model TRFF. Any help 
would be appreciated. :)

Unfortunately, there are only models for the JKFF and the DSFF.  You 
can see them in the code at:
    com.sun.electric.tool.user.CompileVHDL.java
and, if you are enterprising, you can write additional models.
