+Subject: range() of sc_biguint
+From: "Masahiro Taniguchi" <taniguchi.masahiro@lsi.melco.co.jp>

+
+Hi all,
+
+I found a strange simulation result regarding sc_biguint.
+I attached the example about it.
+The example described 3 case.
+ 1. Write non-0
+ 2. Write 0 without cast
+ 3. Write 0 with cast (sc_biguint<8>)
+The wrong result appears in the 2nd case.
+Is this a bug of SystemC?
+
+-------Environment-------
+ SystemC V1.0.2 and V2.0
+ GCC 2.95.2
+ Sun Solaris
