Cytoprotection is a process by which chemical compounds provide protection to cells against harmful agents. For example, a gastric cytoprotectant is any medication that combats ulcers not by reducing gastric acid but by increasing mucosal protection. Examples of gastric cytoprotective agents include prostaglandins which protect the stomach mucosa against injury by increasing gastric mucus secretion.
Integer or Basic Data Types - System verilog has a hybrid of both verilog and C data types. 1  shortint - 2-state SystemVerilog data type, 16-bit signed integer. 2  int - 2-state SystemVerilog data type, 32-bit signed integer. 3  longint - 2-state SystemVerilog data type, 64-bit signed integer.
16'hC501 //an unsigned 16-bit hex value. 16'shC501 //a signed 16-bit hex value. In addition to being able to declare signed data types and values, Verilog 2001 adds two new system functions, $signed and $unsigned. These system functions are used to convert an unsigned value to signed, or vice-versa.
