2625 - Platform Manager II: Is there a limit to the number of state machines implemented in the POWR1220AT8 in PAC-Designer?
The PAC-Designer software limits the number of multiple state machines to 15. In practice the number of macrocells in the POWR1220AT8 will limit the number of state machines to much less. The number of macrocells used per state machine is strongly dependent on the number of states and the number of outputs controlled within the states and varies from design to design.
A good practice for understanding the macrocell impact of various state machine designs in PAC-Designer is to compile the design at regular intervals. Each time the design is compiled, you can see the current macrocell usage by clicking the "Click here to see the fitter report" link displayed after compilation. The "Device Resource Summary" section of the reports includes information abut current macrocell usage.
