CHISEL : Vec - VLSI SPACE- chisel vec ,08-09-2020·CHISEL : Vec. A Vec in chisel represents a collections signal (same type). These are similar to the array data structures in other languages. Each element in Vec can be accessed by an index. A Vec will be created by calling a constructor with two parameters: The combinations vec …Chisel/FIRRTL: General CookbookHow can I tieoff a Bundle/Vec to 0? You can use asTypeOf as above. If you don’t want to worry about the type of the thing you are tying off, you can use chiselTypeOf: import chisel3._ class MyBundle extends Bundle { val foo = UInt(4.W) val bar = Vec(4, UInt(1.W)) } class Foo(typ: Data) extends RawModule { val bundleA = IO(Output(typ)) val ...

Chisel/FIRRTL: Memories

Memories. Chisel provides facilities for creating both read only and read/write memories. ROM. Users can define read-only memories by constructing a Vec with VecInit.VecInit can except either a variable-argument number of Data literals or a Seq[Data] literals that initialize the ROM.. For example, users can create a small ROM initialized to 1, 2, 4, 8 and loop through all values using a ...

val vec_of_elements = Vec(10, Module(SaturatingCounter(4)).io) That works form me. Note the .io, by adding that you are getting some of type Data and you have access to all the ios of the modules you've created here. In general you only need a Vec if you want to use hardware based indexing of the elements, or your Elements are part of an IO.
