Gemmini test have waveform but not have data in it

[Thế Huy]

Hello everyone,

I wrote my own Gemini test in :“bareMetalC/matrix_add"(is attacked below), 

“” https://docs.google.com/document/d/1-67LuUXvv8Bi6kJKa5Q_ISZPiG0fLwDs3EKbHGpjy0k/edit “”

It adds two matrices 2x2 (or n x n) successfully, and generates waveform in "gemmini waveform".  (Exactly the latest waveform). But when I open waveform, enter all signals in PE or Macunit, all signals equals 0( illustrated below):

I wonder whether it compute in other block or not? 

Thank you
