The following command line example shows how sampling a buffered port at a slow rate produces some "tReg full" warnings:
$ cat a.xc
#include
in buffered port:1 p = XS1_PORT_1A;
int main()
{
p :> int;
p :> int;
return 0;
}
$ xcc -target=XS1-L1A-LQ64 sim.xc
$ xsim --warn-resources --debug-ports -t a.xe | \
grep -ePORT12 -elost -emain | \
grep -ePosEdge\ 1 -etRegFull -elost -e'main.*: in' | \
grep 'main.*: in' -A30 -m1 | \
sed 's/.*\(tReg 0x., tRegFull .\).*/\1/' | \
sed 's/.*\(clkBlkPosEdge 1\).*/\1/' | \
sed 's/.*: in.*/in ---/'
in ---

How does --warn-resources work on the simulator? Topic is solved
