+Omit the {{{--gui}}} and end the tcl script with {{{quit}}} to run in batch mode.
+Here is a simple example, to test a 4x4 multiplier with inputs (a,b) and output p:
+
+{{{
+puts "Starting multiplier test"
+set errz 0
+for {set i 0} {$i < 16} {incr i} {
+    for {set j 0} {$j < 16} {incr j} {
+        add_force a -radix dec $i
+        add_force b -radix dec $j
+        run 10
+        set calc_p [expr {$i * $j}]
+        set sim_p [get_value -radix unsigned p]
+        if {$calc_p != $sim_p} {
+            puts "ERROR: Calculated: $calc_p simulated: $sim_p"
+            incr errz
+        }
+    }

+puts "$errz total errors"
+quit
