To ALLIANCE VLSI/CAD SYSTEM TEAM (cao-vlsi@masi.ibp.fr) Sub Alliance tutorial From Bilas Datta (bils@india.ti.com) Hello, This is Bilas from Texas Instruments, India. I have installed "ALLIANCE VLSI/CAD SYSTEM RELEASE 3.0 May 10th 1995" software to practice the software. I have initially started with the tutorials.Out of six,I have already tried the first three : a ADDACCU b AMD2901 c DLX I successfully completed the last two with some minor changes in the path name etc. But for the first one i.e. ADDACCU , I am facing problems. I am describing what I have faced/done: ---------------------------------------------------------------- Step Command Status ---------------------------------------------------------------- Behavior Compilation asimut -b -c addaccu O.K. ---------------------------------------------------------------- Behavior Simulation O.K. & asimut -b addaccu addaccu specifications Validation ---------------------------------------------------------------- Netlist Capture genlib -v core & O.K. genlib -v addaccu ---------------------------------------------------------------- Simulation of the specification asimut addaccu addaccu schema Error 109: Netlist ---------------------------------------------------------------- Error 109 :signal `cki` never assigned cannot continue further more So what I did is, I replaced all "cki" by "ck" and repeated the steps . This time I didn't get the error mentioned above. But in the very next step i.e. core layout generation I faced error again, described below: command: scr -p -r addaccu addaccu Error msg: scr_error,Bad placed instance : p15, or the abutment box is not defined in the genlib file. I couldn't proceed further. I will appreciate your help to solve this problem. Thanks and Regards, Bilas.
