xcomm
English | 中文
xcomm is a C++20 library for hardware simulation, providing four-state signals, port collections, clocks, expressions, temporal events, and functional coverage. Install the Python distribution as uc-xcomm and import it as xspcomm; bindings are also available for Java, Scala, Go, Lua, and JavaScript.
Get started
After installation, create and read a wide signal:
import xspcomm as xs
signal = xs.XData(128, xs.XData.InOut)
signal.value = (1 << 96) + 3
print(hex(signal.value))
The output is 0x1000000000000000000000003. Continue with the tutorial to advance a clock and wait for an event.
