Is clock information allow in C with UVM testbench using DPI?

Is clock(signal from rtl or from testbench) allow to be used in C program to trigger event or delay?

The short answer is yes. However, from the way you worded your question, I'm immediately inclined to use the PLI/VPI instead of the DPI.

 

There are a lot of ways to skin this cat. If you want more guidance, you'll need to give more details about what you're trying to accomplish.

This question is very vague. C programs don't have the concept of event triggers or delays. But SystemVerilog can use event triggers or delays to schedule when you call a C code from the DPI, and C code can in turn call SV code that has event triggers and delays.
