I found a funny bug in quartus_map.
it crash when compiling the following module:
module crashtest(
input clk,
input rst
);
reg loc_reset = 0;
always @(posedge clk or posedge rst) loc_reset <= rst ? 1 : 0;
endmodule
with message Internal Error: Sub-system: VRFX, File: /quartus/synth/vrfx/verific/verilog/verivalue_elab.cpp, Line: 3132 Can't register this value Now rewrite module as follows
module crashtest(
input clk,
input rst
);
reg loc_reset = 0;
always @(posedge clk or posedge rst)
if(rst)
loc_reset <= 1;
else
loc_reset <= 0;
endmodule
and everything compiles fine. also, the module can be rewritten in next form
module crashtest(
input clk,
input rst
);
reg loc_reset = 0;
always @(posedge clk or posedge rst) loc_reset <= rst ? '1'b1 : 1'b0;
endmodule
and it compiles well I think the problem exists in all versions, including the latest 16.0 I'm using web-edition of quartus. Could it affect in such a way?
