Model evaluation and circuit simulation/verification is performed in a graphical processing unit (GPU). A multitude of first texture data corresponding to size parameters of devices are stored. A multitude of second texture data corresponding to instance parameters of the devices are stored. A multitude of third texture data corresponding to models of the devices are stored. A multitude of fourth texture data corresponding to terminal voltages received by the device are stored. A multitude of links linking each device instance to an associated device model, size parameters and instance parameters are stored. A quad having a size defined by the multitude of links is drawn by the quad in the GPU. Each thread in the quad is assigned to a different one of the multitude of links. The computations are carried out in each thread using the linked data to perform the model evaluation.

Model implementation on GPU

An improved cathodoluminescent device with a one piece spacer structure which is rigidly connected to two sets of grid electrodes. The spacer structure defines holes therein that spatially match pixel dots on an anode on a face plate. One set of grid electrodes comprises layers of electrically conductive material on surfaces within at least some of the holes of the spacer structure. The two sets of grid electrodes and different spacer layers may be attached together to form a one piece spacer structure integral with the two sets of grid electrodes. The display device is then simply assembled by matching each of the holes of the spacer structure with a pixel dot on the face plate, and attaching the structure to the face plate and a back plate.
