Cannot load in netlists in Innovus: syntax error？

Hi, when I try to load in design to Innovus, it returns error message:

Reading netlist ...
Backslashed names will retain backslash and a trailing blank character.
**ERROR: (IMPVL-209): In Verilog file '../RTL_codes/models_pack.v', check line 7 near the text @ for the issue: 'syntax error'. Update the text accordingly.
Type 'man IMPVL-209' for more detail.
Verilog file '../RTL_codes/models_pack.v' has errors! See above.

When I type 'man IMPVL-209', it returns : 

IMPVL-209(20.15) IMPVL-209(20.15)

NAME
IMPVL-209

SUMMARY
In Verilog file '%s', check line %d near the text %s for the issue:
'%s'. Update the text accordingly.

DESCRIPTION
This message reports the location of the text causing a warning or
error situation in the input netlist file, which is briefly described
by the last argument text. Update the source text accordingly to
resolve the issue.

IMPVL-209(20.15)

And my code is : 

module LHQD1 (input D, E, output reg Q, QN);
always @(*)
begin
if (E == 1'b1) begin
Q = D;
QN = ~D;
end
end
endmodule

What error message mentioned is 'always @(*)', I cannot find where the syntax error is, can you help me?
