Hi, I have recently downloaded the alliance software package for the SunOS and have successfully loaded and run the software. I am very much impressed. I have a particular interest in using the rom generator(grog). I have in fact created a 4 by 256 memory and translated it to the 'cmos_7' process as a test case. Subsequently I was able to read it in to one of our technologies via the gds interface. I was able to remap the output layers to our technology by editing the cmos_7.rds file. In order to continue I need to set the minimum space and lambda's according to your documentation. In regard to that I saw in your documentation reference to a program "prol" which is supposed to assist in creating the '.rds' file. The program does not appear to be included in the software that I downloaded. Please advise as how to proceed. Thanks for your help. Ken Spicer spicer@atmel.com
