I am trying to use the Modelica_synchronous library (https://github.com/modelica/Modelica_Synchronous). the Library loads just fine but when trying to run to 'check' some of the examples I receive a message like:

[18] 7:51:03 AM Validation of model Modelica_Synchronous.Examples.Systems.ControlledMixingUnit Error: [:0:0-0:0] Error occurred while flattening model Modelica_Synchronous.Examples.Systems.ControlledMixingUnit Error: [C:/Users/fspagna/Downloads/ModelicaSynchronous-0.92-build.2/ModelicaSynchronous 0.92/ClockSignals.mo:642:3-674:11] Class Clock not found in scope Modelica_Synchronous.ClockSignals.Interfaces.

Validation of model Modelica_Synchronous.Examples.Systems.ControlledMixingUnit completed with errors.

The Library Release Notes indicates that:

Release notes• Version v0.92 (2013-09-19) ?The library uses the latest Modelica Standard Libary (MSL) version 3.2.1 (but still works with version 3.2). ?Added a couple of convenience source blocks for Real, Integer, and Boolean signals that are similar to the blocks found in the MSL, but have as output a clocked signal. ?Added a couple of source blocks that are parametrized in terms of clock ticks rather than simulation time. ?All new blocks are utilized in at least one test

So I am confused as to what the problem may be.

Thank you,

Fulvio
