This should return
a=1, but verilator returns
(the MSB should be '1', obviously we don't care about the 'x' in the LSB that
is the result of the (by one bit) out-of-bounds part select):
module issue_057(a, y); input [2:0] a; output [3:0] y; localparam [5:15] p = 51681708; assign y = p[15 + a -: 5]; endmodule
Self-contained test case: test020.v, test020_tb.v, test020.cc, test020.sh
This is with git e8edbad (verilator_3_864).
