Hi there, I have this problem when running a script file in Cadence PKS: The script file reads in a fully-routed design database and then attempts to extract design parasitics using the HyperExtract tool. However, the system crashes and gives a segmentation fault in the Unix terminal window. But, when I run the same script commands separately (all within the PKS environment), i.e. first execute everything up to the HyperExtract command and then when this is done I run the HyperExtract and following commands, the tool does what I expect it to do. The command used to execute Hyperextract is 'hyperExtract' (this is the command used to execute hyperExtract in standalone mode from the Unix command prompt). The documentation talks about using the command 'do_hyperextract' from within PKS but PKS doesn't recognise this and reports an invalid command error. Is there a way of linking in the Unix command into PKS? Moreover, why does the command 'do_hyperextract' not work even though it is mentioned in the SPR flow guide? Many thanks
