Re: black box in system generator

does the module have an active low reset?

Re: black box in system generator

no normal reset only , that means when the reset is '0', the model counts upto 15, since im using a 4 bit counter.

im not able to implement a small "and" gate using black box!!!, i have manually set my and1.config file output(c) to "bool", added my path 's:/.../and1.vhd', still some errors, how to sort this, whats the correct procedure?
