Simulink 6.1 includes the following bug fixes made since Version 6.0. If you are upgrading from a version of Simulink earlier than Version 6.0, you should also see the Major Bug Fixes summary for Simulink 6.0. The following bug fix occurred in Version 6.0 but was not documented in the Version 6.0 release notes.

Wrong Discrete-Time Integrator Reset Behavior

In Simulink 5.0 (Release 13) and 5.1 (Release 13SP1), if the Discrete-Time Integrator block's External reset option is set to level, the block incorrectly resets itself not only when the reset signal is not zero, but also when the signal is falling or rising. In Simulink 6.0 (Release 14) and subsequent releases, the integrator correctly resets itself when the reset signal is not zero.
