The SearchForms and FilterForms are nearly identical to the TriggerForms with only minor changes. The TriggerForms define which samples are stored to memory while running and when the GoLogic triggers. In contrast, the SearchForms and FilterForms operate on trace data which has already been captured. You can either find or remove specific samples in the captured trace data.

Since the SearchForms and FilterForms are nearly identical to the TriggerForms, this chapter does not discuss how to use the forms. See Chapter 4 - Setup step three: triggering for details on how to define the search and filter forms. Instead, this chapter covers the how the search and filter setup differs from the triggering setup.
 

I2C Searching

SPI Searching

The UART, CAN, LIN, and bitstream search/filter forms are exceptions. The GoLogic cannot trigger on these serial buses, so these forms are only available in the Search and Filter tabs. Therefore, the UART, CAN, LIN, and bitstream forms are described in this chapter.

• Go to matching sample - The software scrolls to the sample which matches the SearchForm.
• Count all matches - The software displays a message indicating the total matches in the data.
• Bookmark all matches - A bookmark is placed at each matching sample in the data. To prevent excessive bookmarks, you can limit the total bookmarks in case the SearchForm matches too many samples.
  
• Find next (F3) - Executes the search feature. Finds the next match starting at the active scroll position. The F3 key also executes the search feature.
• Find prev (Shft+F3) - Executes the backwards search feature. Finds the previous match starting at the active scroll position. The Shift+F3 key also executes the backwards search feature.

The "After download" system option can be used with the above search actions. The "After download" system option is located under the "Options > System options..." menu command. Each time a new trace is captured, the software automatically executes the search feature starting at the trigger sample.

• Remove matching samples - Starting at the first sample and ending at the last sample, the software removes each sample which matches the FilterForm.
• Leave matching samples - Starting at the first sample and ending at the last sample, the software removes each sample which differs from the FilterForm.
• Apply Filter - The FilterForm is used to remove/leave all matching samples in the selected source data.

• ID-field - Find a specific ID field in the data.
• ID-field series - Find a consecutive series of ID fields in the data. Ignores non-ID fields.
• Full packet - Find a complete CAN packet in the data.
• Packet series - Find a consecutive series of full CAN packets in the data. Up to 4 full packets can be entered.
• Any error - Finds any error in the data.

The ID-field can use the standard 11-bit form...

...or the extended 32-bit form...

The ID-field can be edited in hexadecimal or binary...

The basic rules for trigger/search patterns apply. The "x" character is an 'anything' placeholder. The bits associated with each "x" can be any value and match the pattern.
 

Up to 8 consecutive ID-fields can be entered...

Each ID-field is defined the same as a single ID-field search.
 

A full packet search allows all fields to be specified...

The number of data bytes in a full packet can vary from 0 to 8. The "any" value ignores any data bytes which may appear in the packet. If you choose a specific number of data bytes and leave all the data values to "x", then the packet must contain the number of data bytes specified, but each data byte can be any value.
 

Up to 4 consecutive full packets can be entered...

Each packet is defined the same as a single full-packet search.
