Multiple Driver Nets Issue with Custom IP

I am building a custom AXI IP using vivado 2018.3 tool and following Xilinx documentations. My IP has few write registers as well as few read registers. Everything work fine if I comment out the read registers but when I uncomment them I get a Multiple Driver Nets issue during implementation. Below is the code snippet in question. I tried set the redRegs port as "out" or "inout" and still same issue. Can you please comment on how I should make this assignment? 

customIP : hecate
generic map (CNTBITS=>CNTBITS)
port map (

CLK => CLK,
Q => Q,
Qb => Qb,
--captures registers
--readRegs(((0+1)*CNTBITS)-1 downto CNTBITS*0) => slv_reg0(CNTBITS-1 downto 0),
--readRegs(((1+1)*CNTBITS)-1 downto CNTBITS*1) => slv_reg1(CNTBITS-1 downto 0),
--readRegs(((2+1)*CNTBITS)-1 downto CNTBITS*2) => slv_reg2(CNTBITS-1 downto 0),
--readRegs(((3+1)*CNTBITS)-1 downto CNTBITS*3) => slv_reg3(CNTBITS-1 downto 0),
configRegs(((0+1)*CNTBITS)-1 downto CNTBITS*0) => slv_reg10(CNTBITS-1 downto 0),
configRegs(((1+1)*CNTBITS)-1 downto CNTBITS*1) => slv_reg11(CNTBITS-1 downto 0),
configRegs(((2+1)*CNTBITS)-1 downto CNTBITS*2) => slv_reg12(CNTBITS-1 downto 0),
configRegs(((3+1)*CNTBITS)-1 downto CNTBITS*3) => slv_reg13(CNTBITS-1 downto 0),

);

Re: Multiple Driver Nets Issue with Custom IP

For that my suggestion is that you will use a USB port and also that will be Toshiba USB port and that you will see that will be fine for all. For further information about it from toshiba error 0xc0000185, browsing this you will get it properly.
