Hi Ludovic, First to all, thanks by your answer. Please answer this message :) I suggest you to have a look on the tutorial of the addaccu. OK. In this tutor, and others, begin with behavioral description,adder.vst and obtain the layout. Design top-down. If you want to use your component myFullAdder in the structural view of your circuit you have to write the behaviour of myFullAdder in a file myfulladder.vbe. I have myfulladder.vbe, and later? If I write: COMPONENT myFullAderr Is .... ENd COMPONENT Alliance take it? I don't need some previous definition? some definition of custom library? I you want a physical view of your circuit you need to create a structural view of your cell myFullAdder (with bop and scmap). I think that I have one problem of sintaxis. Excuse me, if I am not walking in the "legal" way. This is the full history: I have one circuit in version behavioral (.vbe), structural (.vst), netlist (.al) spice (.spi), layout ap and cif. This is one logic combinational circuit. (design top-down) Also, I have edited one layout of one cell, mycell.ap, and have obtained the description behavioral. I have do one trick. I copy the mycell.ap, .al and .vst in the directory of Scell. And edit the file CATAL. Later, write one circuit structural, circuit.vst and call the "standard cell" mycell, like any other cell (nand, or , or some like that). (design down-top ) With this circuit I have obtained one layout!! (design top.down using one custom cell) Alliance put my cell connected to the other standard cells. Alliance take my cell as one Scell. Ok. This look good. Being very much happy, I put this circuit in version .ap, .al and .vbe in the standard cells directory. I was thinking that Alliance take this circuit with two outputs as one Scell, and so, I can invoke it in some structural description. But no was so. This don't work. I have errors in all places. My happiness was coming to the end. I have two custom cells that I can invoke in structural description. I have one circuit that I can't invoke. This circuit have two outputs. My problem is that I have 32 circuits, in description behavioral, circuits.vbe, and I can obtain your version .vst, .sl, .spi, .al. But, I need to describe one circuit that invoke this all 32 circuits an put connected together. I don't know how do it. Thanks newly by your help. I am waiting your opinion, be cool, say me anything that you think about, regardless of any impact, If you think that I have loosed, ok, say me. I will be grateful of any comment!!!
