====== RTL Compiler basic commands ======

UNIX environment setup:

<code>
source /usr/local/config/cds_config/CdsRC_122.rc
</code>



Basic usage:

<code>
rc [-bg] [-dft] [-ctos] [-cmdfile <string>] [-del_scale 10] [-display <display>] 
   [-E] [-execute <string>] [-files <string>] [-lsf_cpus <integer>] [-lsf_queue <string>] 
   [-gui] [-logfile <string>] [-N <integer>] [-no_custom] [-nogui] [-overwrite] [-post <string>]
   [-queue] [-wait <integer>] [-rcl] [-rcp] [-use_license <string>] [-vdi] [-vdi_xl] [-version]
</code>



For a description of various options and switches use ''-help'',

<code>
rc -help
</code>

Log files optional switches (defaults are ''rc.log'' and ''rc.cmd'' created in the same directory where you launch ''rc'')

<code>
mkdir log
rc [-logfile ./log/rc.log] [-cmdfile ./log/rc.cmd]
</code>

Useful alias that can be added to your ''~/.cshrc''

<code>
alias rc 'rc -logfile ./log/rc.log -cmdfile ./log/rc.cmd'
</code> 




\\
RTL Compiler initialization file (if exists)

''~/.cadence/.synth_init''

An empty initialization file just prevent RTL Compiler to show you feedback-related startup messages, 

<code>
touch ~/.cadence/.synth_init
</code>


\\
To list all RC available commads use:

<code>
rc:/> help
</code>



\\
Command types:

   * analysis commands
   * ChipWare commands
   * constraints commands
   * customization commands
   * design manipulation commands
   * design for test (DFT) commands
   * GUI commands
   * general commands (e.g. UNIX-like commands ''lls'', ''lpwd'' etc.)
   * input/output commands
   * low-power commands
   * multiple supply voltage commands
   * navigation commands
   * physical commands
   * read/write structured data-path (SDP) files commands
   * synthesis commands (e.g. ''elaborate'', ''synthesize'')




\\
Automatically generate TCL tempalte control scripts:

<code>
rc:/> write_template [options] -outfile <filename>
</code>

<code>
rc:/> help write_template
</code>

Full template:

<code>
rc:/> write_template -outfile template_full.tcl -full
</code>




:!: **//Note//** \\

The RTL Compiler command prompt understands TCL commands!

<code>
rc:/> puts "Hello world!"
Hello world!
</code>


No help available for native TCL commands,

<code>
rc:/> help source
No matching commands found
</code>

====== Minimal working control script ======

<code>
set_attribute library /path/to/technology/library/libName.lib 
read_hdl -v2001 /path/to/design.v
elaborate
synthesize -to_generic
synthesize -to_map
write_hdl 
</code>
