Programming Questions

This page summarizes a list of questions about writing an application on top of OpenTimer.

---

Q: What language does OpenTimer support?

A: OpenTimer is written in modern C++ and supports only C++ development.

Q: Is OpenTimer thread-safe?

A: Yes, OpenTimer is thread-safe. You can create multiple timer objects in a program, each operating on an unique timing view. People have been doing this for multi-mode multi-corner (MMMC) analysis.

ot::Timer timer1;           # create a timer for one corner
ot::Timer timer2;           # create a timer for another corner
timer1.read_celllib("corner1.lib");
timer2.read_verilog("corner2.lib");
...
timer1.update_timing();     # update the timer for the first corner
timer2.update_timing();     # update the timer for the second corner

It is also safe to spawn two threads each on a timer.

std::thread t1([&] () { ot::Timer timer1; });  # thread 1 to operate timer 1
std::thread t2([&] () { ot::Timer timer2; });  # thread 2 to operate timer 2
