   @tmoreau89 @liangfu @vegaluisjose We tried to update the chisel 
implementation to reflect the new ISA changes, but failed after some trials.
   
   I think it is not trivial to fix it without much knowledge on the chisel 
implementation. It doesn't work by simply changing some defined constants. 
Quite a number of codes have to be changed in order to make it consistent.
   
   I think it would be better to open a new PR later to fix the chisel codes. 
It is ideal that the chisel implementation can kind-of auto-derive the hardware 
parameters from the vta C++ headers. This restructure of the chisel code needs 
the help from @vegaluisjose, and is not very related to this PR. 
   
   So I think maybe we disable the tsim test and merge this PR first since the 
changes in the VTA repo already merged. And open a new PR to fix the chisel 
implementation. What do you think?
   
   Thanks
