Abstract
According to some embodiments, an eye pattern evaluation device configured to communicate with a host includes a first interface circuit configured to acquire an eye pattern. The eye pattern evaluation device includes a controller configured to control the first interface circuit and a non-volatile memory. The controller determines whether a reception count number at a predetermined point included in the acquired eye pattern reaches a threshold value, and records, in the non-volatile memory, log information indicating communication quality at the predetermined point when the reception count number at the predetermined point reaches the threshold value.

An eye pattern evaluation device configured to communicate with a host, comprising:
- a first interface circuit configured to acquire an eye pattern;
- and
- a controller configured to control the first interface circuit and a non-volatile memory;
- wherein the controller:
- determines whether a reception count number at a predetermined point in the acquired eye pattern reaches a threshold value;
- and
- records, in the non-volatile memory, log information indicating communication quality at the predetermined point when the reception count number at the predetermined point reaches the threshold value.
An system, comprising:
- an interface configured to acquire an eye pattern;
- and
- a controller configured to:
- control the interface and a memory;
- determine whether a reception count number at a predetermined point in the acquired eye pattern reaches a threshold value;
- and
- record, in the memory, log information indicating communication quality at the predetermined point when the reception count number at the predetermined point reaches the threshold value.
