|Home > Iris APIs > Simulation accuracy (sync levels)|
Some target instances support adjusting the trade-off between simulation speed and accuracy, by using a synchronization level or sync level.
syncLevel_release() functions request and release
a minimum sync level. Calling
syncLevel_request( ensures that the effective
sync level is at least
syncLevel_release( must be called for every call
syncLevel_request( when the
requested sync level is no longer required. This might cause the
sync level to decrease, and therefore increase the simulation speed,
depending on the sync levels requested by other users.
Requesting and releasing a sync level of zero is valid but has no effect. The sync level of a particular target instance is a shared resource. It is not possible to set a specific sync level, except the highest one, because another client might be using a higher sync level.
Target instances that do not support requesting sync levels must
