[vlsi-nastava:2004] - visoka impedansa by "Ivan Ivanovic" <ivan2000@eunet.yu>

Kako da izlazni signal postavimo u stanje visoke impedanse. Receno mi je da
moze sa 'z' ali se to ne moze iskompajlirati. Npr

int_data_out <= (others => 'z');

prijavljuje greske:

Error: COMP96_0077: data_bus_buffer.vhd : (31, 29): Assignment target
incompatible with right side. Expected type "std_ulogic".
Error: COMP96_0079: data_bus_buffer.vhd : (31, 19): Invalid aggregate.
Error: COMP96_0104: data_bus_buffer.vhd : (31, 19): Undefined type of
expression.

pozdrav
