PETrainer Scripting Language

33

Note:

Command supported only by Z3 Trainer.

5.8 Link = Detect

Tells the PETrainer™ to immediately bring the Link down. In this state, the LTSSM drives all of the
PCI Express lanes to electrical idle. Before the lanes go to electrical idle, a single electrical idle ordered
set is transmitted. Applies while in any state.
Note:

Command supported only by Z3 Trainer.

5.9 Link = LTSSMOff

Disables the LTSSM. This essentially means that the PETrainer is not responsible for managing the link
state. Instead, the user is free to transmit ordered sets, DLLP's, and RAW packets blindly.
Note: Command only supported by ML and EML Trainers.

5.10 Link = InitFC

Starts the flow control initialization state machine.

5.11 Link = PERST

Sends a PERST# signal for the period specified.

5.12 Link = PERST_Assert

In host mode, the Z3 trainer will drive a low in the bus for PERST#.
Note:

Command supported only by Z3 Trainer.

5.13 Link = PERST_Deassert

In host mode, the Z3 Trainer will release PERST# and the bus will drive PERST# high.
Note:

Command supported only by Z3 Trainer.

5.14 Link = 2_5

Initiates speed switch to 2.5 GT/s data rate. The system attempts to switch if the link is in the L0 state at
5.0 GT/s data rate.
Note: This command only applies to the Summit Z2-16 and Summit Z3-16 Trainers.
