I cannot find an example in the Simics documentation on how the clock object is obtained so that we can use it as an argument in the post() method.
I suspect that either
- an attribute can be used to get the clock or
- in the ConfObject class scope we get the clock using SIM_object_clock()
I created a new module using bin\project-setup --py-device event-py
I have defined two methods in the ConfObject class scope called clock_set and clock_get.
I wanted to use these methods so that I can set/get the clock object to use in the post method.
The post() method fails when reading the device registers in the vacuum machine.
