http://palms.ee.princeton.edu/system/files/Chisel+Overview.pdf WebMar 9, 2024 · One feature of a Vec[Bool] is that testing the values of each bit is simple. For example, let's say I have a module that gives back a UInt. I want to test a particular bit is set but I don't care what the other bits are. With a Vec[Bool] I could easily do this: dut.io.v(bit).expect(true.B) Is there an equivalent using UInt?
