ConstantBus Properties
The ConstantBus is a simplified bus model that does not model the interaction between simultaneous messages on the bus medium. It has different modes:
- instant mode: messages are transmitted with no delay.
- constant_time mode: every message has a constant delay.
- constant_rate mode: every message has a transmission time proportional to its size.
| Entry | Unit | Type | Description | Default Value |
|---|---|---|---|---|
type |
S | Must be constant_bus for a ConstantBus. Must be the first entry. |
||
mode |
S |
instant, constant_rate or constant_time. |
||
time |
s | Duration | Time to transmit one message when in constant_time mode. | |
rate |
bytes/sec | FP | The transmission rate when in constant_rate mode. |
CAN Properties
The CAN EE-component models a bus using the CAN bus protocol.
| Entry | Unit | Type | Description | Default Value |
|---|---|---|---|---|
type |
S | Must be can_bus for a CAN bus. Must be the first entry. |

bit_rate |
bits/s | I | Transmission rate of the bus. | 10 Mbits/s |
