Module for a TTEthernet Host. Contains a EtherLLC for best-effort traffic, a TTEPHYPort module as physical port, sync module (Sync) and a TTEScheduler module. The Host is configured by the provided TTEthernet XML network configuration (network_configuration parameter) and uses the device_name parameter to find its config. The configuration is done by the BufferManager that deletes itself at runtime.

Name | Type | Default value | Description |
---|---|---|---|
phy.tteOutput.tt_buffers | string | "" |
Comma seperated list of TTBuffers that send messages to this port |
phy.tteInput.ct_marker | int | 0 |
Critical traffic marker of the buffer |
phy.tteInput.ct_mask | int | 0 |
Critical traffic mask of the buffer |
phy.tteInput.incomings | string | "" |
Comma seperated list of ctc modules the input uses |
phy.mac.address | string | "auto" |
MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0. |
phy.mac.duplexMode | bool | true |
must be set to "true", as EtherMACFullDuplex does not support half-duplex operation (parameter is present to reduce the risk of accidental misconfiguration) |
phy.mac.txQueueLimit | int | 1000 |
maximum number of frames queued up for transmission in the internal queue (only used if queueModule==""); additional frames cause a runtime error |
phy.mac.mtu | int | 1500B | |
cli.destAddress | string | "" |
destination MAC address, or module path name of destination station; empty means off |
cli.startTime | double | this.sendInterval |
time of sending the first request |
cli.stopTime | double | 0 |
time of finish sending, 0 means forever |
cli.sendInterval | double | uniform(0s,1s) |
interval between sending requests |
cli.reqLength | int | 100B |
length of request packets |
cli.respLength | int | 1KiB |
length of response packets |
tteScheduler.tick | double | 80ns |
Length of a tick |
tteScheduler.max_drift | double | 16ps |
Maximum clock drift (e.g 16ps for 200ppm at 80ns per tick) |
tteScheduler.max_drift_change | double | 1ps |
Maximum clock drift change per cycle |
tteScheduler.cycle_ticks | int | 37500 |
Number of ticks for one cycle |
tteApp.buffers | string |
Comma seperated list of buffer modules the application is allowed to use |
|
bgIn.destination_gates | string | "" |
Priority of the buffer (currently only used for rate-constrained traffic) int priority=default(-1); Critical traffic ID of the buffer int ct_id=default(0); Critical traffic marker of the buffer int ct_marker=default(0); Critical traffic mask of the buffer int ct_mask=default(0); Comma seperated list of gates where the frames of the buffer are delivered |
bgIn.size | int | -1 |
Size of the buffer negative means infinite |
bgIn.drop_new | bool | false |
Dropping policy, Should the newest frame instead of the oldest frame be dropped when the buffer is full (see size parameter) |
bgOut.destination_gates | string | "" |
Priority of the buffer (currently only used for rate-constrained traffic) int priority=default(-1); Critical traffic ID of the buffer int ct_id=default(0); Critical traffic marker of the buffer int ct_marker=default(0); Critical traffic mask of the buffer int ct_mask=default(0); Comma seperated list of gates where the frames of the buffer are delivered |
bgOut.size | int | -1 |
