I'm a student of Informatic Engeneering and i have to develop a
little project with your tool (i have alliance 3.2b). Now i have a
problem. With this file:
entity MULTIPLEXOR is
port ( enable, selec: in bit;
in1: in bit_vector(3 downto 0);
in2: in bit_vector(3 downto 0);
out1: out bit_vector(3 downto 0)
);
end MULTIPLEXOR;
architecture ARCHMULT of MULTIPLEXOR is
begin
process(enable,in1,in2)
begin
if (enable='0') then
out1<="1111"
else
if (enable='1') then
if (selec='0') then
out1<=in1
else
out1<=in2;
end if;
end if;
end if;
end process;
end ARCHMULT;
And the command: >asimut -b -c multiplexor
I obtain the next error:
Initializing ...
Searching multiplexor ...
BEH : Compiling multiplexor.vbe (Behaviour) ...
multiplexor.vbe Error line 11 : parse error
multiplexor.vbe Error 18 line 20 :illegal concurrent statement
