WebOct 29, 2013 · Chisel gets angry if your variables do not have default values (i.e., there is a path through your logic in which a variable will not get set, since Chisel does not support X's/don't cares). Although you can ditch most of that code and probably just write this if you don't mind the extra port: http://www2.imm.dtu.dk/courses/02139/02_basic.pdf fis sites

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? http://palms.ee.princeton.edu/system/files/Chisel+Overview.pdf
