malformed statement in verilog3
verilog call module inside always block
the code doesn't Works. I am getting "Malformed statement" error. Can you guys help me? it appears in ring_c1 module instantiation. Thanks in advance.
module log2(N,clk); `include "parameters.vh" input [7:0] N; reg [7:0] aux ; reg [7:0] last_log; reg [7:0] div_last; output reg [7:0] y; // assign aux = N; input clk; parameter high = 1; always @ (posedge clk) begin ring_c1 ri1 ( aux, div_last); aux = aux >> 1; if (aux < 1 ) begin ring_c1 r1v ( high, div_last); log_Finale (last_log, div_last); y = y + last_log; end else y = y+1; end endmodule
You can't instance components in an always statement.
You have to place them outside the always and then use them.

To expand on @Oldfart's comment: You are trying to write RTL (register transfer language) as if it was a programming language expect with module instantiation instead of function calls--it isn't. You are using code to describe real hardware, gates, flip-flops, banks of memory, etc. If you can't envision the hardware that your code will produce, you're doing it wrong. You can't have hardware appear and disappear in real time based on signals in your design. However, you can have the modules instantiated and use multiplexer logic to design which module outputs you wish to use.
