uvm_recorder

[gustn]

Does anyone have an example of how exactly to use uvm_recorder?

Can I use them to call the vendor-specific transaction recording and visualize them in the waveforms?

Within Any verification component.

// Start transaction recording.

void'(this.begin_tr(MonDataItem, "MonitorDataItem"));

.....

this.end_tr(MonDataItem);

From 'UVM test class'

// Enable transaction recording.

set_config_int("*", "recording_detail", UVM_FULL);

Regards,

Thanks Barindra,

Hello Gustn,

The ubus monitor files, located in the UVM installation at examples/integ/ubus/sv show when/where to use the begin_tr/end_tr and associated syntax. You can also find usage of transaction recording in the UVM Reference Flow (download from the uvmworld contributions area). If you download this example - you can find the APB UVC example in $UVM_REF_HOME/soc_verification_lib/sv_cb_ex/interface_uvc_lib/apb. Transaction recording is done in the collector and the monitor.

Now - for vendor-specific transaction recording. The Cadence version of UVM includes built-in transaction recording and transactions will automatically be recorded if you point to this version and use the set_config_int("*", "recording_detail", UVM_FULL); syntax shown above.

Good Luck!

This so-call "Hooks" mechanism only records transactions from sequencers automatically when you turn on the recording scheme.

As I know, Information could be recorded as below list.

1. Stream name,scope

2. Transaction name ,begin and end time.

3. Attribute name and value

4. Relation between sub-sequence and sequence
